A charge 3 mu C is released at rest from...

A charge `3 mu C` is released at rest from a point P where electric potential is (20 V). Find its kinetic energy when it reaches inifinity.

Text Solution

Verified by Experts

`W_(el) = Delta K = K_(f) - 0`
`W_(el))_(P rarr oo) = qV_(P) = 60 mu J`
so, `K_(f) = 60 mu J`
