Given below is the plot of a potential energy function $\displaystyle U(x)$ for a system, in which a particle is in one dimensional motion, while a conservative force $\displaystyle F(x)$ acts on it. Suppose that $\displaystyle \mathrm{E}_{\text {mech }}=8 \mathrm{~J}$, the incorrect statement for this system is :
[ where K.E. = kinetic energy ]
[ where K.E. = kinetic energy ]Official answer
(2)
at $\displaystyle x<x_1$, K.E. is smallest and the particle is moving at the slowest speed.
