A child pulls a box with a force of 200 Newton at an angle of 30 degrees above the horizontal.Then the horizontal and vertical components of force are:

A)173N,100N

B)86.6N,100N

C)100N,86.6N

D)100N,0N

ans is A................

200 cos 30 is horizontal component

200 sin 30 is vertical component

x component of F will be cos= 200cos30= 173

y component of F will be =200 sin 30=100

thus ans is A....................173,  100
