A force of 20 newtons is exerted on a chair from its right and a force of 12 newtons is applied from its left. What is the net force acting on the chair and in what direction will the chair tend to move?
Fn=12 - 20 = -8 N.=8 N. To the left.
So the chair will move to the left.
To find the net force acting on the chair, we need to determine the sum of the forces acting in different directions. In this case, we have a force of 20 newtons to the right and a force of 12 newtons to the left.
Since the forces are in opposite directions, the net force can be found by subtracting the smaller force from the larger force. So, 20 newtons (larger force) minus 12 newtons (smaller force) equals a net force of 8 newtons to the right.
Therefore, the net force acting on the chair is 8 newtons to the right. This means that the chair will tend to move in the direction of the net force, which is to the right.
