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 -

Correct Answer is : 4πε0Q×1022volt∕m

4 \pi \epsilon_0 {\Q} \times 10^{20} {\volt} \/ {\m}

12 \pi \epsilon_0 {\Q} \times 10^{22} {\volt} \/ {\m}

4 \pi \epsilon_0 {\Q} \times 10^{22} {\volt} \/ {\m}

12 \pi \epsilon_0 {\Q} \times 10^{20} {\volt} \/ {\m}
