D) \[1/{{R}^{2}}\]
Correct Answer: A
Solution :
Key Idea: Since sphere is moving with constant velocity, there is no acceleration in it. When the sphere of radius^ is falling in a liquid of density a and coefficient of viscosity \[\eta \] it attains a terminal velocity v, under two forcesYou need to login to perform this action.
