normal

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

A

$x = x_1$

B

$x = x_2$

C

both $x_1$ and $x_2$

D

neither $x_1$ nor $x_2$

Solution

For equilibrium $F = 0$

and slope of $F\,v/s\, x $ be

negative $\Rightarrow x_2$ is stable equilibrium
