A particle moves in one dimension in a conservation force field. The potential energy is depicted in the graph below. If the particle starts to move from rest from the point `A`, thenA. the speed is zero at the point `A` and `E`.B. the acceleration vanished at the point `A,B,D,C,E`C. the acceleration vanished at the points `B,C,D`D. the speed is maximum at the point `D.` |

Answer» Correct Answer - A::C `V_(A)+K_(A)=V_(E)+K_(E)` `V_(A)=V_(E) & K_(A)=0 :. K_(E)=0` `F=(dV)/(dx)=0`, Slope `=0` at points `B,C,&D` Ans. `(AC)` |
