(B) The electric potential $V$ at a point is defined as the work done by an external agent in moving a unit positive charge from infinity to that point without any change in kinetic energy.Formula: $V = \frac{W_{ext}}{q}$Given:Work done $W_{ext} = 20\,\mu J = 20 \times 10^{-6}\,J$Charge $q = 2\,\mu C = 2 \times 10^{-6}\,C$Calculation:$V = \frac{20 \times 10^{-6}}{2 \times 10^{-6}} = 10\,V$Therefore,the potential at that point is $10\,V$.
