Question

The electric potential at a point in free space due to charge Q coulomb is Q $ \times $ 10¹¹ volts. The electric field at that point is

$4\pi {\varepsilon _0}Q \times {10^{20}}$ volt/m

12$\pi $₀Q $ \times $ 10²² volt/m

$4\pi {\varepsilon _0}Q \times {10^{22}}$ volt/m

$12\pi {\varepsilon _0}Q \times {10^{20}}$ volt/m
