A small uncharged conducting sphere is placed in contact with an identical sphere but having $4 \times 10^{-8} \, C$ charge and then removed to a distance such that the force of repulsion between them is $9 \times 10^{-3} \, N$ . The distance between them is (Take $\frac{1}{4\pi \epsilon_0} = 9 \times 10^9$ in SI units):

A
$2 \, cm$
B
$4 \, cm$
