Work Energy And Power Question 302
Question: The force acting on a body moving along x-axis varies with the position of the particle as shown in the figure. The body is in stable equilibrium at:
Options:
A) $ x=x_1 $
B) $ x=x_2 $
C) both $ x_1 $ and $ x_2 $
D) neither $ {x_1} $ nor $ x_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] If a particle at $ x_1 $ is displaced slightly towards left or right the force is in the same direction.
Hence the equilibrium is unstable.
Whereas at $ x_2 $ the force is directed opposite to displacement.
