A force 10N acts in the direction 060° and another force 6N acts in the direction 330°. Find the y component of their resultant force.
(3+3√3)N
(−3+5√3)N
(5+3√3)N
(5+5√3)N
Correct answer is B
F=Fcosθ+Fsinθ (Resolving into its components)
10N=10cos60,10sin60
6N=6cos330,6sin330
R=F1+F2=(10cos60,10sin60)+(6cos330,6sin330)
The y- component : 10sin60+6sin330=10×√32+6×−12
= (5√3−3)N
