Question

Two forces whose resultant is 100N are perpendicular to each other. If one of them makes an angle of 60° with the resultant, calculate its magnitude.

Answer 1

F1 = 100*Cos60 = 50 N.

Answer 2

86.6

Answer 3

Fx=100cos60°
Fx=100×0.5
Fx=86.60
Corret answer is E

Answer 4

For those choosing 86.6N and 50N, pls indicate because the both answer are under the option given below
