Q. If a point charge $q$ is placed at a point inside a hollow conducting sphere, then which of the following electric lines of force pattern is correct?
A) [image:2_image46.emf]
B) [image:2_image47.emf]
C) [image:2_image48.emf]
D) None of these
Explanation
(b) Presence of point charge (+$q$) induces negative charge on inner surface of hollow conducting sphere and positive charge on outer of sphere. Hence, field lines will be directed radially outward from surface of sphere as shown in(b)
