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.

asthenosphere and convection

cant without the picture! ?
