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 E mech =8J, the incorrect statement for this system is:
Text Solution
Verified by ExpertsThe correct answer is:
B
E mech =8J
at x > x 4 , U = constant = 6 J
K = E mech − U = 2 J = constant
at x < x 1 , U = constant = 8 J
K = E mech. − U = 8 − 8 = 0 J
Particle is at rest.
At x = x 2 , U = 0 ⇒ E mech. = K = 8 J
KE is greatest, and particle is moving at fastest speed.
x = x 3 , U = 4 J
At U + K = 8 J
K = 4 J
