Find force acting between two shells of ...

Find force acting between two shells of radius `R_(1)` and `R_(2)` which have uniformly distributed charges `Q_(1)` and `Q_(2)` respectively and distance between their centres is r.

Text Solution

Verified by Experts

The shells can be replaced by point charges kept at centre, so force between them

`F=(KQ_(1)Q_(2))/r^(2)`
