Answer:
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 |
