A charge of magnitude Q is divided into two parts. If the force between the resultant two charges is maximum when separated through some distance R, the charge of the two parts is
1
\(\frac{3Q}{8}, \frac{5Q}{8}\)
2
\(\frac{Q}{2}, \frac{Q}{2}\)
3
\(\frac{Q}{8}, \frac{Q}{4}\)
4
\(\frac{3Q}{4}, \frac{Q}{4}\)
