A particle with the potentila energy shown in the graph is moving to the right. It has 1.0J of kinetic energy at x=1.0m. Where the particle reverses its direction of motion?

Options

A. 4
B. 6
C. 2
D. 5

Answer

B

Explanation

At `x=1.0m, U=3.0J` and `K=1.0J` so total mechanical energy E=K+U=40J
Particle reverses its direction where K=0
Therefore reverses its direction where K=0
Therefore at this point U=4.0J `rArrx=6.0m`
