Question
Two blocks of masses m and 2m are placed on a smooth horizontal surface as shown. In the first case, only a force F1 is applied from the left. Later only a force F2 is applied from the right. If the force acting at the interface of the two blocks in the two cases is the same, then F1 : F2 is ______
Options
1:1
1:2
2:1
1:3
Solution
Two blocks of masses m and 2m are placed on a smooth horizontal surface as shown. In the first case, only a force F1 is applied from the left. Later only a force F2 is applied from the right. If the force acting at the interface of the two blocks in the two cases is the same, then F1 : F2 is 2:1.
