A ball of mass 1 kg carrying a charge `10^(-8)C` moves from a point A at potential 600 V to a point B at zero potential. The change in its kinetic energy is

A

`-6xx10^(-6)`erg

B

`-6xx10^(-6)J`

C

`6xx10^(-6)J`

D

`6xx10^(-6)` erg

Text Solution

Verified by Experts

The correct Answer is:
C
As work is done by the field K.e. of the body increases by
`K.E.=W=q(V_(A)-V_(B))=10^(-8)(600-0)=6xx10^(-6)J`
