The force acting on a body moving along x-axis varitian of the particle particle shown in the figure. The body is in stable equlilbrium 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

(b) When displaced from `x_(2)` in negative direction, force is positive. So, this force is restoring in nature and will bring the body back. Hence, at `x_(2)` body is in stable equilibrium position.
