In the diagram, two friends are pushing a box on a frictionless surface as shown below. Which direction will the block move?
West
The forces applied by two friends are opposite in direction. The resultant force acting on the box will be equal to the difference of magnitude between the two forces and it will act in direction of the greater force. Hence, the box will experience a net force of 3N (= 10N - 7N) in west direction. So, it will move towards west.
