A small sphere of radius ' 
' falls from rest in a viscous liquid. As a result, heat is produced due to viscous force. The rate of production of heat when the sphere attains its terminal velocity, is proportional to -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
We know from stoke's Formula that Terminal velocity of a body in viscous fluid 
also 
also heat developed(H) is due to the power requied to slow the body by the fluid
