Q1. Two identical 30 {rm g} particles each carry 3.0 {rm mu C} of charge. One is held fixed, and the other is placed 1.0 {rm mm} away and released. Find out the speed of the moving charge when it's 1.0 {rm cm} from fixed charge.
Q2. An 82 kg parachutist descends through a vertical height of 350 m with constant speed. Find out the increase in entropy produced by the parachutist; assume the air temperature is 21 degrees C.
