In the millikan oil drop experiment the measured charge of any single droplet was always a whole number multiple of -1.60 x 10-19 c. if a single droplet was found to have a total charge of -9.60ã—10-19 c then how many excess electrons are contained within the drop?

Number of electrons, n = 6

Explanation:

Total charge in a single droplet,

The measured charge of any single droplet,

Let n is the number of excess electrons are contained within the drop. According to the quantization of charge :

n = 6

So, there are 6 electrons contained within the drop. Hence, this is the required solution.

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)

it is called kinetic energy
