Dear student,

In the experiment, the oil drop with excess charges on it is kept in the air due to electric force on it by keeping between plates with a potential difference between them.

Under equilibrium,

$mg=qE$
$\implies \rho(\dfrac{4}{3}\pi r^3)g=q\dfrac{V}{d}$
$\implies V=\dfrac{4\rho \pi r^3 dg}{3q}$
