How many rice grains are needed for an electric charge of a certain strength (I dont remember the value now but is it really relevant?) to be equally distributed amongst them?

I hope you can answer that :)

The exact value of the charge is very important. If it turns out to be precisely 3 times the charge on an electron, we know that 3 rice grains are needed.
