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

Text Solution

Verified by Experts

Net charge enclosed by the sphere is -2Q
Electric flux through the sphere `=-(2Q)/epsilon_0`
