Q. Which one of the following graphs, shows the variation of electric field strength E with distance d from the centre of the hollow conducting sphere?
A) [image:1_image145.emf]
B) [image:1_image146.emf]
C) [image:1_image147.emf]
D) [image:1_image148.emf]
Explanation
(d) Inside hollow sphere, $E = 0.$ on the surface of hollow sphere, $E =$ maximum and outside the sphere, $E \propto 1/r^{2}.\ $this is shown in figure (d).
