In a Millikan-type experiment, two horizontal charged plates are 2.5 cm apart. A latex sphere of 1.3x10^-15 kg remains stationary between the plates when the potential difference between the plates is 400 V. The upper plate is charged positive and the bottom is negative. What is the charge on the sphere? And how many excess elementary charges are on the sphere?

#### Top Answer
