A juggler throws two balls up to the same height so that they pass each other halfway up when A is rising and B is descending. Ignore air resistance and buoyant forces. Which statement is true of the two balls at that point?a. The only force acting on each ball is the gravitational force. b. There is an residual upward force from the hand on each ball. c. Only gravity acts on B but there is an additional residual force from the hand on A. d. There is a greater residual force from the hand on A than there is on B. e. There is an additional downwards force besides gravity on each ball.
