A hand pushing a 18.2 kg block. The two blocks, 18.2 kg and 22.0 kg, are attached to a string and move along a frictionless surface. Which of the following is true? Assume the string to be massless.
1. The force of the string on the 22.0 kg block is smaller than the force of the hand on the 18.2 kg block.
2. The force of the string on the 22.0 kg block is larger than the force of the hand on the 18.2 kg block.
3. The force of the string on the 22.0 kg block is equal to the force of the hand on the 18.2 kg block
