1.

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 points A, B, C, D, EC. 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
