Given that mass of particle m = 10mg
Charge 1 = – 0.01μC
A = 100cm2 Let potential = V
The Equation capacitance C = 0.04/2 = 0.02μF
The particle may be in equilibrium, so that the wt. of the particle acting down ward, must be balanced by the electric force acting up ward.

∴ qE = Mg
Electric force = qE = q(V/d)

where V – Potential, d – separation of both the plates.

 

Now put qE = mg

You will get answer as 43 MV

Then you will get answer approx 43
