The charge on the droplet must be
Explanation:
In order for the oil droplet to be in equilibrium, the force of gravity acting on it (the weight, acting downward) must be equal to the electrical force acting upward.
The gravitational force is:
which is equivalent to the weight of the droplet.
The electric force is given by:
where
q is the charge on the oil droplet
is the magnitude of the electric field
Since the two forces must be equal,
And solving for q,
