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

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
c
Field lines do not enter the metaillic portion of the shell as field is zero inside the metal . Hence options (a) and (d) are incorrect .
The field lines are normal to metal surface.
Hence option (b) is incorrect. Both the conditions are satisfied in option (e ) . Hence (c ) represents the correct answer.
