Question
An object is under the action of three forces, one (150 N from its front side and the rest (74 N and 54 N) from its back side. The net force on it is ___ N.
Hint:
An object is under the action of three forces, one (150 N from its front side and the rest (74 N and 54 N) from its back side. The net force on it is 22 N.
The correct answer is: 22
- The sum of all the forces applied to an object is called net force.
- The forces with the same direction can be added to derive the net force.
- If the forces from various directions are not equal, the force that has less magnitude can be subtracted from that of high magnitude.
- If the object is subjected to 150 N force from one side and 74 N, 54 N forces from the opposite side, the forces of the same direction can be added and the total can be subtracted from the force of the opposite side.
- 150 N - (54 N + 74 N)+ 22 N
