Question
An object is pulled from opposite sides with forces, as shown. Find the net force acting on the object by taking the positive reference direction towards the right.
- +360 N
- -360 N
- +76 N
- -76 N
Hint:
142-218= -76N
The correct answer is: -76 N
- As of here, we have to take force towards right direction as applying force.
- So, 142 N will be of positive magnitude.
- Hence, net force = 142 N + (- 218) = -76 N.
- Object will move towards left direction as force applied towards left is greater than right.
