The electric potential at a point in free space due to a charge Q coulomb is \[Q\times {{10}^{11}}V\]. The electric field at that point is [AIPMPT (S) 2008]

\[12\pi {{\varepsilon }_{0}}Q\times {{10}^{20}}V/m\]

\[4\pi {{\varepsilon }_{0}}Q\times {{10}^{22}}V/m\]

\[4\pi {{\varepsilon }_{0}}Q\times {{10}^{20}}V/m\]

\[12\pi {{\varepsilon }_{0}}Q\times {{10}^{22}}V/m\]
