Assignments

 

1. An oil drop of 12 excess electrons is held stationary under a constant electric field of 2.55 x 104V/m in Millikan’s oil drop experiment. The density of the oil drop is 1.26 cgs units. Estimate the radius of the oil drop.

 

2. Use the simulation and find out the charge on any five drops. By comparing the charges on the drops, find out the charge on an electron?

 

3. Why bubbles are rising up through water or any other liquid?

 

4. Why tiny drops becomes clouds where as bigger drops fall as rain?

 

5.Calculate the terminal velocity of an olive oil drop and then its radius.
