Can you solve these physics riddles? ft Simone Giertz - Part 1/3

since the force of air resistance is a function of speed of the balls. now the ball with higher terminal velocity will have more frictional force. since terminal velocity is directly proportional to the difference in density of the object and the surround medium therefore the ball with more mass will have greater density for same shape dimensions hence the heavier ball will experience more frictional force.
