Question

The figure below shows a graph of potential energy $U\left(x\right)$ 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 :-

• 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 1

Answer: (C)

$F=-\frac{dU}{dx}$
$K+U=E$
