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.

A.

(3+33)N

B.

(3+53)N

C.

(5+33)N

D.

(5+53)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

= (533)N
