Question

The figure below shows two forces A=15 N and B=5 N acting on an object. What is the

resultant force on the object?

Answer 1

18.03 N

Step-by-step explanation:

From the fiqure below,

Using parallelogram law of vector

R² = 15²+5²-2×5×15cos(180-60)

R² = 225+25-150cos120°

R² = 250-150(-0.5)

R² = 250+75

R² = 325

R = √325

R = 18.03 N

Hence the resultant force of the object is 18.03 N
