1.	If a raindrop with a mass of 0.05 g falls with constant velocity, the retarding force of atmospheric frictionis (neglect density of air) …………… .
Answer» zero 49 dynes 490 dynes none of these Solution :Since the RAIN drop is falling with constant velocity , the retarding upwards force is equal to its WEIGHT in magnitude, `F = 0.05 xx 980 = 49` dynes
