1.	A drop of water of radius 10^(-5) m is falling through a medium whose density is 1.21 kg m^(-3) and coefficient of Viscosity 1.8xx10^(-4) poise. Find the terminal velocity of the drop.
Answer» Solution :` v= 2 XX ( 10 ^(-5)^(2)xx (1000- 1.21)xx 9.8//9 xx 1.8 xx 10 ^(-3)= 1.2 xx 10 ^(-2)MS ^(-1)`
