Physics Paragraph Questions

Mechanics

Passage 1: (JEE Advanced 2023) Consider a projectile launched with initial velocity v at angle with horizontal. The projectile experiences air resistance proportional to its velocity, given by F = -kv, where k is a constant. The motion can be analyzed using differential equations and terminal velocity concepts.

Q1. The terminal velocity of the projectile is: (a) v cos/k (b) mg/k (c) kv/mg (d) v sin/k

Q2. The time taken to reach 50% of terminal velocity is: (a) (m/k) ln 2 (b) (m/k) ln(2) (c) (m/k) ln(3/2) (d) (m/k) ln(5/4)

Solution: Terminal velocity occurs when drag force equals weight: mg = kv_terminal v_terminal = mg/k For velocity approach: v = v_terminal(1 - e^(-kt/m)) At v = 0.5v_terminal: 0.5 = 1 - e^(-kt/m) e^(-kt/m) = 0.5 -kt/m = ln(0.5) = -ln(2) t = (m/k) ln(2)

Answers: Q1: (b), Q2: (a)

Passage 2: (JEE Advanced 2022) A uniform rod of length L and mass M is pivoted at one end and allowed to swing freely in a vertical plane. The rod is displaced by small angle and released, performing simple harmonic motion. The moment of inertia about the pivot point is I = ML/3, and the restoring torque is = -mg(L/2)sin.

Q3. The time period of oscillation is: (a) 2(3L/2g) (b) 2(L/3g) (c) 2(2L/3g) (d) 2(L/g)

Q4. For small angle approximation, the angular frequency is: (a) (3g/2L) (b) (3g/L) (c) (g/3L) (d) (2g/3L)

Solution: For simple harmonic motion: = -I For small angles: sin H mg(L/2) = (ML/3) = (3g/2L) Angular frequency: = (3g/2L) Time period: T = 2/ = 2(2L/3g)

Answers: Q3: (c), Q4: (a)

Electromagnetism

Passage 3: (JEE Advanced 2023) A parallel plate capacitor with plate area A and separation d is filled with a dielectric slab of dielectric constant K and thickness t (< d). The remaining space (d-t) is vacuum. The system can be treated as two capacitors in series: one with dielectric (C) and one without dielectric (C).

Q5. The equivalent capacitance is: (a) A/[d-t + t/K] (b) AK/[t + (d-t)K] (c) A[d/(Kt) + (d-t)/d] (d) A[1/(d-t) + K/t]

Q6. If t = d/2 and K = 4, the capacitance becomes: (a) (4/3)A/d (b) (8/3)A/d (c) (2/3)A/d (d) (6/5)A/d

Solution: Series capacitors: C = KA/(t) and C = A/(d-t) 1/C = 1/C + 1/C = t/(KA) + (d-t)/(A) C = A/[t/K + (d-t)]

For t = d/2, K = 4: C = A/[(d/2)/4 + (d/2)] = A/[d/8 + d/2] = A/[(5d/8)] = (8/5)A/d

Answers: Q5: (a), Q6: (b)

Chemistry Paragraph Questions

Physical Chemistry

Passage 4: (JEE Advanced 2023) The Haber process for ammonia synthesis operates under specific conditions: temperature 450-500C, pressure 150-300 atm, and iron catalyst with promoters. The reaction N(g) + 3H(g) 2NH(g) is exothermic (H = -92 kJ/mol). Le Chatelier’s principle explains how equilibrium shifts with changes in conditions.

Q7. Increasing temperature will: (a) Shift equilibrium to the right (b) Shift equilibrium to the left (c) Not affect equilibrium position (d) Increase the rate constant

Q8. The optimum pressure range represents a balance between: (a) Reaction rate and equilibrium position (b) Catalyst efficiency and temperature (c) Product yield and production cost (d) Safety considerations and reaction rate

Q9. The role of iron catalyst with promoters is to: (a) Increase equilibrium constant (b) Lower activation energy (c) Shift equilibrium to products (d) Increase reaction enthalpy

Solution: The reaction is exothermic, so increasing temperature shifts equilibrium left (Le Chatelier). High pressure favors fewer gas molecules (products), but too high pressure increases cost. Catalysts lower activation energy and increase rate, but don’t affect equilibrium position.

Answers: Q7: (b), Q8: (c), Q9: (b)

Organic Chemistry

Passage 5: (JEE Advanced 2022) The SN1 reaction mechanism involves two steps: first the formation of a carbocation intermediate (slow, rate-determining step), followed by nucleophilic attack (fast step). The rate depends only on the substrate concentration, not the nucleophile concentration. The stability of carbocation determines the reaction rate.

Q10. For the reaction CHCHCl + HO CHCHOH + HCl, the rate law is: (a) Rate = k[CHCHCl][HO] (b) Rate = k[CHCHCl] (c) Rate = k[CHCHCl] (d) Rate = k[HO]

Q11. Among the following substrates, which will react fastest in SN1 mechanism? (a) CHCHCHCHCl (b) (CH)CCl (c) CHCHCl (d) CHCl

Solution: SN1 rate depends only on substrate concentration. Tertiary carbocation (from (CH)CCl) is most stable due to hyperconjugation and inductive effects.

Answers: Q10: (c), Q11: (b)

Mathematics Paragraph Questions

Algebra

Passage 6: (JEE Advanced 2023) Consider the quadratic equation x + px + q = 0 with roots and . The sum and product of roots are related to coefficients by Vieta’s formulas: + = -p and = q. Various expressions involving roots can be simplified using these relationships.

Q12. The value of + is: (a) p - 2q (b) p + 2q (c) q - 2p (d) q + 2p

Q13. If and are roots of x - 5x + 6 = 0, then + is: (a) 91 (b) 35 (c) 125 (d) 91

Solution: For x + px + q = 0: + = ( + ) - 2 = (-p) - 2q = p - 2q

For x - 5x + 6 = 0: Roots are 2 and 3 + = 2 + 3 = 8 + 27 = 35

Answers: Q12: (a), Q13: (b)

Calculus

Passage 7: (JEE Advanced 2022) The definite integral +[a,b] f(x)dx represents the area under the curve y = f(x) between x = a and x = b. For polynomial functions, integration can be performed using the power rule: +xdx = xz/(n+1) + C. Definite integrals evaluate to specific numerical values when limits are applied.

Q14. The value of +[0,1] (3x + 2x + 1)dx is: (a) 1 (b) 2 (c) 3 (d) 4

Q15. If +[0,2] f(x)dx = 10 and +[0,1] f(x)dx = 3, then +[1,2] f(x)dx is: (a) 5 (b) 7 (c) 10 (d) 13

Solution: +[0,1] (3x + 2x + 1)dx = [x + x + x] = 1 + 1 + 1 = 3

+[0,2] f(x)dx = +[0,1] f(x)dx + +[1,2] f(x)dx 10 = 3 + +[1,2] f(x)dx +[1,2] f(x)dx = 7

Answers: Q14: (c), Q15: (b)
