Question

A metallic solid sphere is placed in a uniform electric field. The lines of force follow the path(s) shown in Fig. as

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is D $4$

The electric lines of force cannot enter the metallic sphere as electric field inside the solid metallic sphere is zero. Also, the origination and termination of the electric lines of force from the metallic surface is normally (directed towards the centre).

Hence only path 4 is correct, because it is directed towards the centre.
