Question

I want explanation and answer both ​

Answer 1

Answer:

From the given information if total energy is E and potential energy is U(x)

Kinetic energy K(x) = E - U(x)

Also, Conservative force the field is given by

F = - dU(x)/dx

If dU(x)/dx = 0 then at that point F = 0

When force F = 0 then acceleration a = 0

Option (D)
