Question

If a raindrop with a mass of 0.05 g falls with constant
velocity, the retarding force of atmospheric friction is
(neglect density of air):
A Zero
B. 49 dynes
C. 490 N
D. 49 N​

Answer 1

Answer:

Work done = mgh

m = mass of drop = 0.1 g = 0.00001 kg

g = 9.8 m/s

h = 100 m

work done = 0.00001 x 9.8 x 100

= 0.098 J
