Question

A charge Q is enclosed by two concentric spherical surface of radii R and 2R.what is the ratio of flux through each sphere?

Answer 1

ratio should be 1 because flux does not depends on radious

Answer 2

Given :

A charge Q is enclosed by two concentric spherical surface of radii R and 2R .

To Find :

The ratio of flux through each sphere .

Solution :

We know , flux is given by :

$\phi=\dfrac{Q}{\epsilon_o}$

Now , it is given that both the sphere encloses the same charge .

So , flux will be same in both the sphere .

Therefore , the ratio of flux through each sphere is 1 .
