Question

A charge $Q$ is to be divided on two objects. The values of the charges on the objects so that the force between the objects can be maximum are

• A. $\frac{2Q}{3},\frac{Q}{3}$
• B. $\frac{3Q}{4},\frac{Q}{4}$
• C. $\frac{Q}{2},\frac{Q}{2}$
• D. $O$

Answer 1

Answer: (C)

$\frac{Q}{2},\frac{Q}{2}$

Answer 2

So, force between the objects is maximum for $\frac{Q}{2},\frac{Q}{2}$ .
