In the diagram, two friends are pushing a box in opposite directions as shown below. In which direction will the block move?
West
The forces applied by two friends are opposite in direction. The net force acting on the box will be a difference between the two forces in the direction of the greater force.
The difference in forces = 10 - 7 = 3N. Also, the force with the greater magnitude (10 N) acts in the west direction.
Hence, the box will experience a net force of 3N in west direction. So, it will move towards the west.
