Answer

10 Newtons West Explanation 1. Combine forces in the North-South direction Net North-South force = (3 N North + 18 N North) − (3 N South + 18 N South) = 21 N − 21 N = 0 N 2. Combine forces in the East-West direction Net West force = (7 N + 2 N + 6 N) − 5 N East = 15 N − 5 N = 10 N West 3. Determine net force magnitude and direction Only 10 N West remains; no North-South component.

Explanation

1. Combine forces in the North-South direction <br /> Net North-South force = (3 N North + 18 N North) − (3 N South + 18 N South) = 21 N − 21 N = 0 N <br /><br />2. Combine forces in the East-West direction <br /> Net West force = (7 N + 2 N + 6 N) − 5 N East = 15 N − 5 N = 10 N West <br /><br />3. Determine net force magnitude and direction <br /> Only 10 N West remains; no North-South component.
