An oil drop, whose mass is found to be 4.95 x 10-15 kg, is balanced between two large, horizontal parallel plates 1.0 cm apart, by a potential difference of 510 V, with the upper plate positive. What is the charge on the drop, both in coulombs and in ele
Two point charges, one of charge + 2.5 x 10-5 C and other of charge - 3.7 x 10-5 C, are 25 cm apart.
In a Millikan-type experiment, two horizontal charged plates are 5 cm apart. A sphere of 2 x 10-17 kg remains stationary between the plates when the potential difference between the plates is 12 V.
