Question
A student pushes horizontally on two blocks. The blocks are moving to the right. Block A has more mass than block B. There is no friction between the blocks and the table. For the situation where the blocks are speeding up, which of the following statements is true about the magnitude of the forces?
The force that block A exerts on block B is greater than the force that block B exerts on block A.
The force that block A exerts on block B is less than the force that block B exerts on block A.
The force that block A exerts on block B is equal to the force that block B exerts on block A.
We cannot compare the forces unless we know how fast the blocks are speeding up.
Explanation / Answer
By the Newton's third law, both will be exerting equal and opposite force on each other. As the Newton third law states that there is an equal and opposite reaction when a force is applied.
