Question

Force acting on a particle moving along $x-$ axis is as shown in figure. Points of stable and unstable equilibrium are

• A. A,C
• B. B,D
• C. A,B
• D. C,D

Answer 1

The correct option is A A,C

The points at $x=0$ indicates the point of stable equilibrium i.e. $A$ while at $x>0$, i.e. at $C$ represents the point of unstable equilibrium since, the displacement of particle $\left(towardsD\right)$ disturbs its equilibrium.
