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 Emech = 8 J, the incorrect statement for this system is :
Correct Option: , 2
Solution:
$\mathrm{E}_{\text {mech. }}=8 \mathrm{~J}$
Particle is at rest.
(C) At $x=x_{2}, U=0 \Rightarrow E_{\text {mech. }}=K=8 \mathrm{~J}$
KE is greatest, and particle is moving at fastest speed.
