Question

Which of the following graphs shows the variation of electric field E due to a hollow spherical conductor of radius R as a function of distance from the centre of the sphere?

Answer 1

Answer:

A

Explanation:

electric field inside the hallow sphere is 0.

and outside varies in the function given E=kq÷r^2. as Eis inversely proportional to r^2 the graph will be like hyperbola from value r greater than R.

Answer 2

A)

In a uniformly charged conducting sphere,

electric field inside E=0 No charge is enclosed inside the conductor.

Outside E= $\frac{kq}{r^2}$

​

As E is inversely proportional to $r^2$ therefore, the graph is a hyperbola outside the hollow spherical conductor.

∴Outside it decreases uniformly,

So graph (A) is correct.
