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.
