Forces F1 and F2 are applied to the body, with F1 = 30 mN and F2 = 50 mN. What is the modulus of their resultant, if the angle between the forces is 60 degrees?
The resultant is equal to the sum of all forces acting on the body:
F = (F1 + F2) cosA;
F = (30 mN + 50 mN) * cos60 = 80mN * 1/2 = 40 mN
Answer: 40 mN.
