The electric potential at a point in free space due to a charge Q coulomb is Q x 10¹¹ V. The electric field at that point is

\(4 \pi \epsilon_{G} \mathrm{Q} \times 10^{22} \mathrm{~V} / \mathrm{m}\)
\(12 \pi \epsilon_{a} \mathrm{Q} \times 10^{20} \mathrm{~V} / \mathrm{m}\)
\(4 \pi \epsilon_{\mathrm{G}} \mathrm{Q} \times 10^{2 \mathrm{~A}} \mathrm{~V} / \mathrm{m}\)
\(12 \pi \epsilon_{a} \mathrm{Q} \times 10^{22} \mathrm{~V} / \mathrm{m}\)

Answer

(A) 4 _ G Q 10^ 22 ~V / m
