Two concentric spherical shells of radius `R_(1)` and `R_(2) (R_(2) gt R_(1))` are having uniformly distributed charges `Q_(1)` and `Q_(2)` respectively. Find out total energy of the system.

Text Solution

Verified by Experts

The correct Answer is:
`Q_(1)^(2)/(8 pi epsi_(0) R_(1))+Q_(2)^(2)/(8 pi epsi_(0)R_(2))+(Q_(1)Q_(2))/(4 pi epsi_(0) R_(2))`
