Two balls of same mass and carrying equal charge are hung from a fixed support of length $\displaystyle l$. At electrostatic equilibrium, assuming that angles made by each thread is small, the separation, $\displaystyle x$ between the balls is proportional to :
Official answer
(4)
$\displaystyle l^{1 / 3}$
