Question

A particle is released from rest at the point $x=a$ and moves along the $x$ axis subject to the potential energy function $U(x)$ shown. The particle:

• A. moves to a point to the left of $x=e$, stops, and remains at rest
• B. moves to a point to $x=e$, then moves to the left
• C. moves to $x=b$, where it remains at rest
• D. moves to $x=e$ and then to $x=d$, where it remains at rest

Answer 1

Answer: (B)

Correct answer is (b) moves to a point to $x=e$, then moves to the left
