Question

A thin spherical shell of radius R has charge Q spread uniformly over its surface. Which of the following graphs, most closely represents the electric field E(r) produced by the shell in the range 0 ≤ r < ∞, where is the distance from the centre of the shell :

Answer 1

Correct Option (a)

Explanation :

Inside the shell (r = 0 to r = R), E = 0 on the surface of he shell (r = R), E = max outside the shell, (r > R), E∞1/r²
