Question 931: Electrostats & Capacitance

Question

A conducting sphere of radius R is given a charge Q. The electric potential and the electric field at the centre of the sphere rrespectively are

Accepted Answer

For the conducting sphere,
Potential at the centre = Potential on the sphere
$$ = {1 \over {4\pi {\varepsilon _0}}}{Q \over R}$$
Electric field at the centre = 0

Answer

zero and $${Q \over {4\pi {\varepsilon _0}{R^2}}}$$

Answer

$${Q \over {4\pi {\varepsilon _0}R}}$$ and zero

Answer

$${Q \over {4\pi {\varepsilon _0}R}}$$ and $${Q \over {4\pi {\varepsilon _0}{R^2}}}$$

Answer

both are zero
