Question

Determine the net force is the object (represented by the solid circle) in this diagram.

A) 100 N to the right

B) 200 N to the left

C) 300 N to the left

D) 400 N to the right

Answer 1

Answer : The correct option is, B) 200 N to the left

Explanation :

If the two forces are acting on an object in the opposite directions and they do not exactly cancel each other then the net force is calculated by the difference in the forces.

$F_{net}=F_{left}-F_{right}\\\\F_{net}=300-100=200N$

The force act on an object in the left side are greater than the right side. So, the net force is 200 N to the left.

Therefore, the correct option is, B) 200 N to the left
