Give the magnitude and direction of the net force acting on (a) a drop

1.	Give the magnitude and direction of the net force acting on (a) a drop of rain falling down with a constant speed, (b) a cork of mass 10 g floatingon water, (c) a kite skillfully held stationary in the sky, (d) a car moving with a constant velocity of 30 km/h on a rough road, (e) a high-speed electron in space far from all material objects, and free of electric and magnetic fields.
Answer» Solution : (a) to (d)No net FORCE according to the First LAW (e)No force, since it is FAR awayfrom all material agencies producing electromagnetic and gravitational FORCES.
