Question
Find the net force on the rope in the situation given below.
- 14 N towards the right
- 27 N towards the left
- 54 N towards the left
- 43 N towards the right
Hint:
If two forces act on an object in the same direction, the net force is the sum of the two forces.
The correct answer is: 14 N towards the right
- Net force in left side = 72N + 59N + 43 N = 175 N towards left direction.
- Net force in right side = 36N + 63N + 89N = 198 N towards right direction.
- Hence, it is tug of war both the parties will be applying force opposite to each other and object will move towards the direction where force would be greater.
- The force applied towards right direction is more.
- Net force = - 175 N + 189 N = 14 N towards right direction.
