1.	A glass of radius 10^(-3) and density 2000 kg m^(-3) fall in a jar filled with oil of density 800 kg m^(-3) .The terminal velocity is found to be 1 cm/s. Calculate the coefficient of viscosity of oil
Answer» Solution :` eta= ( 2 XX 10 ^(-3) )^(2)(2000 - 800 )xx 9.8 //9 xx 1 xx 10 ^(-2) =0.26 NS m^(-2)`
