Question
Solve the following numerical problem.
Two force of 12 N and 25 N act on a body to the left-hand side, while another force of 35 N acts on it to the right-hand side. Find the resultant of the forces.
Solution
Total forces acting to the left = 12 N + 25 N = 37 N
Force acting to the right = 35 N
The resultant force on the body = difference between the magnitude of the forces = 37 N – 35 N = 2 N
The object will move in the direction in which the force of 37 N is being applied, i.e., the resultant force of 2 N will act to the left.
