Two forces 10N and 6N act in the directions 060° and ...
Two forces 10N and 6N act in the directions 060° and 330° respectively. Find the x- component of their resultant.
5√3−3
3−5√3
5−3√3
3√3−5
Correct answer is A
F=Fcosθi+Fsinθj
10N=10cos60i+10sin60j
6N=−6cos330i−6sin330j
Rx=10cos60−6cos330
= 10×12−6×√32
= 5−3√3
