Question

Four forces are being applied to move an object to the left. Force 1 is pushing to the right at 200N. Force 2 is pushing to the left at 500N. Force 3 is pushing to the right at 100N. Force 4 is pushing to the left at 50N. What's the net force acting on this object?

A.0N
B.650N
C.850N
D.250N

Answer 1

The answer is D.250N
You start at Zero since no force is being applied to the object. If you move it one way, it starts the positive force. Go another way harder, it becomes a negative force. What I did here was 0+200-500+100-50. It will come out as a negative but you could ignore that because you cannot have a completely negative force as a final result.

Answer 2

250N

Step-by-step explanation:

Force may be defined as a push or pull of an object. Force can change the shape, size and movement of any object.

Net force = Total force acting on left - Total force acting on right

Net force=Force 2 + Force 4 - Force 1 + Force 3

Net force=(500+50) - (200+100)

Net force= 250 N.

Thus, the correct answer is option (D).
