JEE PYQ: Magnetic Effects Of Current Question 29
Question 29 - 2020 (09 Jan 2020 Shift 1)
A charged particle of mass $m$ and charge $q$ moving under the influence of uniform electric field $E\hat{i}$ and a uniform magnetic field $B\hat{k}$ follows a trajectory from point P to Q as shown in figure. The velocities at P and Q are respectively $v\hat{i}$ and $-2v\hat{j}$. Then which of the following statements (A, B, C, D) are the correct?
(1) (A), (C), (D)
(2) (B), (C), (D)
(3) (A), (B), (C)
(4) (A), (B), (C), (D)
Show Answer
Answer: (3) (A), (B), (C)
Solution
(A), (B), (C) are correct. (D) is wrong since $|\Delta L| = 3mva \neq 2mva$.
