The electric potential at a point in free space due to change Q coulomb is {\Q} \times 10^{11} {\V}. The electric field at that point is

Correct Answer is : 4πε0Q×1022V∕m

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

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

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

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