A total charge Q is broken in two parts \[{{Q}_{1}}\] and \[{{Q}_{2}}\] and they are placed at a distance \[R\] from each other. The maximum force of repulsion between them will occur, when [MP PET 1990]

\[{{Q}_{1}}=\frac{Q}{2},\ {{Q}_{2}}=\frac{Q}{2}\]

\[{{Q}_{2}}=\frac{Q}{R},\ {{Q}_{1}}=Q-\frac{Q}{R}\]

\[{{Q}_{2}}=\frac{Q}{4},\ {{Q}_{1}}=Q-\frac{2Q}{3}\]

\[{{Q}_{2}}=\frac{Q}{4},\ {{Q}_{1}}=\frac{3Q}{4}\]

A total charge Q is broken in two parts \[{{Q}_{1}}\] and \[{{Q}_{2}}\
