Question

when two electrons are transferred from one conductor to another potential differnce of 20 v exists between calculate the capacitance of two conductor systems

Answer 1

Dear Student

Total charge on on two conductor system is
$$\begin{gathered} Q=ne=2\times 1.6\times {10}^{-19}C=3.2\times {10}^{-19}C \\ V=20Volt \\ C=\frac{Q}{V}=\frac{3.2\times {10}^{-19}C}{20V}=0.16\times {10}^{-19}F \end{gathered}$$
