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

Text Solution

Verified by Experts

Here, only the charge `-2Q` is enclosed by the sphere of radius 3a so, By Gauss therom
`phi_(E) = (-2Q)/(in_(0))`
