Question
The forces exerted on a tank by two people from opposite directions are shown in the figure below. Find out the net force on the tank taking the positive reference direction towards the left?
- +279 N
- -279 N
- +73 N
- -73 N
Hint:
176-103= 73N (positive)
The correct answer is: +73 N
- On tank to opposite forces is being applied from different direction.
- We have to consider force applied towards left direction as applying force.
- So, 176 N will be in postive magnitude.
- Hence, net force = 176 N + (- 103 N ) = +73 N.
