Question : 73

Total: 100

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 =8J, the incorrect statement for this system is:

[27 Jul 2021 Shift 2]

at x>x4,K.E. is constant throughout the region.
at x<x1,K.E. is smallest and the particle is moving at the slowest speed.
at x=x2,K.E. is greatest and the particle is moving at the fastest speed.
at x=x3,K.E.=4J
