Question

A metallic shell has a point charge $q$ kept inside its cavity. Which one of the following diagrams correctly represents the electric lines of force ?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

We know that the net electric field is zero everywhere inside a metal (conductor). But, options $\left(a\right),\left(b\right)$ and $\left(d\right)$ are showing electric lines inside the metallic part.
So, based on the above assumption of the hypothetical concept of electric field lines, the most appropriate answer is $\left(c\right)$.
