The figure below shows a graph of potential energy U(x) verses position x for a particle executing one dimensional motion along the x axis. The total mechanical energy of the system is indicated by the dashed line. At t=0 the particle is somewhere between points A and G. For later times choose the correct statement:-

Options

A. The magnitude of force is maximum at D
B. The kinetic energy is maximum at B
C. The velocity is zero at A `&` G
D. The magnitude of force is minimum at F

Answer

C

Explanation

`F=(dU)/(dx)` and K+U=E
