The force acting on a body moving along x-axis variation of the particle particle 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)`

Answer

B

Explanation

`F=0 at x=x^(2)`. When displaced from `x_(2)` in negative direction, force is positive i.e. in the opposite direction of displacement. displacement. Similarly, when displaced in positive dirction, force is negative.
