1. 1/2 points 1 Previous Answers My Notes An oil drop whose mess is determined to be 3.43 x 1015 kg is held at rest between two large plates separated by 1.0 cm when the potential difference between them is 300 V. How many excess electrons does this drop have? Ater changing the voltage and dstance betreen the plates, this o After changing the voltage and distance between the between them now?

Explanation / Answer

for constant velocity, net force = 0
q*V/d = m*g
(7*1.6*10^-19)*V/(0.02) = 3.43*10^-15* 9.81
V = 600.9 V
Answer: 600.9 V
