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 tha `E_("mech")=8` J, the incorrect statement for this system is :

A

at `xgtx_(4)`, K.E. is constant throughout the region.

B

at `xltx_(1)` K.E. is smallest and the particle is moving at the slowest speed.
