Question

A charged oil drop remains stationary when situated between two parallel metal plates 25 mm apart and a pd of 1000V is applied to the plates. Find the charge on the oil drop if it has a mass of 5 x 10-15kg.Also calculate the number of basic charge present.

Answer 1

ANSWER-

charged oil drop remain stationary when situated between two parallel plates 20 mm apart and a p.d. of 500 V is applied to the plates. Find the charge on the drop if it has mass of 2×10^-4 kg. Given a charged oil drop remains stationary between 2 parallel plates 20 mm apart...
