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

Answer» Correct Answer - B 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` |
