A conducting sphere of radius \(R\) is given a charge \(Q\). The electric potential and field at the centre of the sphere respectively are:
1.  Zero and \({Q} / 4 \pi \varepsilon_{0} {R}^2\)
2. \({Q} / 4 \pi \varepsilon_{0} {R}\) and zero
3. \({Q} / 4 \pi \varepsilon_{0} {R}\) and \({Q} / 4 \pi \varepsilon_{0}{R}^2\)
4.  Both are zero
