2 0 m s The force of buoyancy exerted by the atmosphere on a balloon is B in the upward direction and remains constant The force of air resistance on the balloon acts opposite to the direction of velocity and is proportional to it The balloon carries a mass M and is found to fall down near the earth s surface with a constant velocity v How much mass should be removed from the balloon so that it may rise with a constant velocity v
