Well we all know that action is equal in magnitude and opposite in direction to reaction.
|F| = m g = 8.7 * 10^-7 * 9.81 = 8.53*10^-6 Newtons
A raindrop has a mass of 8.7 × 10-7 kg and is falling near the surface of the earth. Calculate the magnitude of the gravitational force exerted (a) on the raindrop by the earth and (b) on the earth by the raindrop.
