How terminal velocity depends on the radius of the falling body?

Two rain drops of same radius r falling with terminal velocity v merge and from a bigger drop of radius R. The terminal velocity of the bigger drop is

Assertion : Terminal velocity is same as the critical velocity. Reason : The constant velocity of fall of a body through a viscous fluid is called terminal velocity.

Define terminal velocity and obtain an expression for the terminal velocity in case of a sphere falling through a viscous liquid. Also show graphically the variation of velocity with time.
