Question

the force acting on a body moving along x-axis varies with the position of a particle as shown in figure the body is in stable equilibrium at

Answer 1

i think the answer is

x=x^2

Answer 2

At position x = x1, the force is zero

At position x >x1 the force is positive which means repulsive and therefore the body will not return

At position x>x2 the force is negative which means attractive and thus the body will return to its initial position

Hence option b is right
