alleryTwo friends push a heavy box from the same side, applying forces of 30 N and 40 N in the same direction. What is the net force on the box?
A1200 N
B70 N
C35 N
D10 N
Answer & Solution
Correct answer: B. 70 N
Forces acting on an object in the same direction add up.
Net force = 30 N + 40 N = 70 N, in the direction of the push.
Distractor 10 N would be the answer if the forces were in opposite directions, and 1200 N is the product, which is not how forces combine.
