Question

Given below is the plot of a potential energy function U (x) for a system, in which a particle is in one dimensional motion, while a conservative force F(x) acts on it. Suppose that $\mathrm{E}_{\text {mech }}$ = 8 J, the incorrect statement for this system is :

Select the correct option:

A

at $x>x_4, K . E$. is constant throughout the region.

B

at $\mathrm{x}<\mathrm{x}_1, \mathrm{~K} . E$. is smallest and the particle is moving at the slowest speed.

C

at $\mathrm{x}=\mathrm{x}_2, \mathrm{~K} . E$. is greatest and the particle is moving at the fastest speed.

D

at $x=x_3$ K.E. $=4 \mathrm{~J}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.
