A metallic shell has a point charge 'q' kept inisde its cavity. Which one of the following diagrams correctly represents the electric lines of forces?

A

(a)

B

(b)

C

(c)

D

(d)

Text Solution

Verified by Experts

The correct Answer is:
C
Electric field everywhere inisde the metallic portion of shell is zero.
Hence option (a) and (d) are incorrect.
Electric field lines are always normal to a surface. Hence option (b) is incorrect. Only option (c) represents the correct answer.
