the vertical component of a force is200N . The force makes an angle of 30° with the horizontal. calculate the force

1. F sin 30 = 200 N

|F| = 400 N

F = 400 cos 30 i + 400 sin 30 j
or since you did not say what quadrant the force is in
F = 400 cos 30 i - 400 sin 30 j
or
F = -400 cos 30 i + 400 sin 30 j
or
F = -400 cos 30 i - 400 sin 30 j

I assume that amit means at MIT ?
