Question
Two charges of magnitudes −3Q and + 2Q are located at points (a, 0) and (4a, 0) respectively. What is the electric flux due to these charges through a sphere of radius ‘5a’ with its centre at the origin?

Solution
Gauss’ theorem states that the electric flux through a closed surface enclosing a charge is equal to `1/epsi_0`times the magnitude of the charge enclosed.
The sphere enclose charge = -3Q + 2Q = -Q
Therefore, `phi= Q/epsi_0`
