Question

A drop of water of volume 5×10^-8 meter-cube falls from a height 100m. what is the work done by gravitational force??​

Answer 1

Answer:

1 cubic meter is equal to 852.11336848478 kilo gram which is nearly equal to 1000 kilo gram..

5 x 10^-8 cubic metre

=5 x 10^-8 x 1000 =5 x 10^-5 kg..

height = 100 m..

mass is 5 x 10^-5kg

work done is mgh

5 x 10^-5 x 10 x 100 = 5 x 10^-2 = 0.05 joules..

hope this will help you..
