Determine the magnitude of the force for each direction. A. Add the forces that are applied in the same direction. B. Subtract forces applied in the opposite direction

A)  R = F1 + F2

B) R = | F1 - F2 |

Explanation:

A) For forces acting in the same direction

we will add up the forces : lets assume the forces to be F1 , F2

Then the magnitude of the forces acting in the same direction will be

R = F1 + F2

B) For forces acting in the opposite direction

we will subtract the forces i.e. stronger force - weaker force . assuming the forces to be F1 , F2

Hence the magnitude of the resultant force = R = | F1 - F2 |
