Q. An uncharged sphere of metal is placed inside a charged parallel plate capacitor. The lines of force will look like
A) [image:2_image7.jpeg]
B) [image:2_image8.emf]
C) [image:2_image9.emf]
D) [image:2_image10.emf]
Explanation
(a) When metal sphere is placed inside a charged parallel plate capacitor, the electric lines of force will not enter the metallic conductor as $E = 0$inside a charged conductor. Moreover, the surface of a charged conductor is an equipotential surface and hence, electric lines of force are always perpendicular to equipotential surface.
