Two charges of magnitudes `-2Qand+Q` are located at points (a,0) and (4a,0) respestively . 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

Gauss .s theorem states that the electric flux through a closed suface enclosing charges is equal to `(1)/(epsilon_(0))` times the magnitude of the charge enclosed.
The sphere enclosed a charge of `-2Q`,so
`phi=(2Q)/(epsilon_(0))`
