In this question, we're asked to describe the milliken oil drop experiment and how he was able to calculate the mass of the electron using the results.
00:12
So let's just look at how the experiment works.
00:17
I'll be explaining this in brief steps.
00:21
So basically what happens is first oil is passed through the atomizer and it is released into the chamber through tiny oil droplets.
00:39
Then these droplets, they will pass through the hole.
00:48
So as you can see, there is a hole right here and this is where they pass through and they enter the chamber.
00:57
And then this leads to the downward movement of these oil particles and this is due to the gravity.
01:13
So here they observe that there was downward movement and also they also observed the mass of the oil droplets.
01:28
And then finally what they did, they measured the terminal velocity.
01:43
Then what they did they applied a constant electric field which is denoted by e bar and this is due to collisions of electric charge...
