Problem

A total charge of

20\ \mu\text{C}

is divided into two parts and placed at some distance apart. If the charges experience maximum coulombian repulsion, the charges should be: (a)

5\ \mu\text{C}, 15\ \mu\text{C}

(b)

10\ \mu\text{C}, 10\ \mu\text{C}

(c)

12\ \mu\text{C}, 8\ \mu\text{C}

(d)

\frac{40}{3}\ \mu\text{C}, \frac{20}{3}\ \mu\text{C}
