The electric potential at a point in free space due to a charge

Q

coulomb is

Q \times 10^{11}

volts. The electric field at that point is: (2008) (a)

12\pi\epsilon_0 Q \times 10^{22}

volt/m (b)

4\pi\epsilon_0 Q \times 10^{22}

volt/m (c)

12\pi\epsilon_0 Q \times 10^{20}

volt/m (d)

4\pi\epsilon_0 Q \times 10^{20}

volt/m
