- For a conducting spherical shell of radius R that carries a charge Q, the electric field inside the shell is zero.
- And outside the shell, the electric field behaves as if all the charge Q is concentrated at the center of the shell.
- Thus, the electric field outside the shell, at a distance r from the center, is given by Coulomb's law:
E = kQ/r2
where k is the Coulomb constant.
Therefore, the electric field outside the shell varies inversely with the square of the distance from the center of the shell.
That is, as the distance from the center of the shell increases, the electric field strength decreases rapidly.
So, the plot of electric field w.r.t the distance "r" would be,
The correct answer is option "2"
