Question
List all the forces acting on the block B in figure.
Solution
Forces acting on block B :
- A pair of electromagnetic forces between the blocks A and B.
- A pair of electromagnetic forces between the blocks B and the Earth.
- A pair of gravitational forces between the blocks B and the Earth.
- A pair of gravitational forces between the blocks A and B.
- A pair of action-reaction forces between the man and block A.
- Weight of the man, block A and block B as action forces on the ground in the downward direction.
- Reaction of the ground on the man, block A and block B in the upward direction to balance their weights.
