An uncharged sphere of metal is placed inside a charged parallel plate capacitor. The lines of force will look like |
a) | b) |
c) | d) |
(a)When metal sphere is placed inside a charged parallel plate capacitor, the electric lines of force will not enter the metallic conductor as 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. |
