Question

F1 = (150g) dyne, θ1 = 20 & F2 = (200g) dyne, θ2 = 80

Determine the magnitude & the direction of the resultant force:

Analytically: (Components method)

I dont understand what they mean in g dyne?
And how to know which fx or Fy is cos or sin

Answer 1

mass is given in grams so force will be in dyne.Here, force is representing in dyne force on 150g and 200g.
