Question

Figure shows three point charges +2q, −q and + 3q. Two charges + 2q and −q are enclosed within a surface ‘S’. What is the electric flux due to this configuration through the surface ‘S’?

Solution

The net electric flux through the surface ‘S’ is`q/epsi_0`, where `epsi_0 `is the permittivity of free space.
