Question:
A charge of + 7 uC is placed at the centre
of two concentric spheres with radius 2.0
cm and 4.0 cm respectively. The ratio of
the flux through them will be
Explanation:
As charge is placed at the center of both concentric spheres so, charge is surrounded by both spheres from all sides. Hence, whole flux will pass through both of the spheres in equal amount. As a result, the flux ratio will be 1:1. So, right answer is D.
