Question

The force acting on particle moving along x-axis varies with position on x-axis as shown in figure. The particle is at stable equilibrium at 1. X=-X1
2.X=X2
3. X=0
4.Both 1 & 2

Answer 1

Answer:

The correct answer will be option 2 , X = X2

Explanation:

According to the problem the particle is moving along with x axis , let the force f acting on it.

Now according to the diagram we can see that when the particle starts moving from origin and reaches at x = x1 position the force is zero

and when the particle moves the distance of x>x1 the force is positive

Therefore the force is going further and will not return back

again when the particle starts moving from origin and reaches at x = x1 position the force is zero but at this position the force is negative.

therefore equilibrium is stable here.
