Given:-
- force= 400N
- at angle 60°
To Find:-
- Southward and northward components of force.
Solution:-
Southward component will be written as Fcos60° and eastward component can be written as Fsin60°
Putting values:-
southward component= 400 x cos60°= 400 x 1/2=200N
eastward component = 400 x sin60° = 400 x √3/2= 200√3
Additional informatio
- cos 30° =√3/2
- sin30°=1/2
- sin15°=
- cos15°=
- cos90°=0
- sin90°=1
