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`, then

A

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.`

Text Solution

Verified by Experts

The correct Answer is:
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)`
