Vectors numerical, HELP !

  1. Jul 2, 2012 #1
    A force of 5N is acting along y axis,its component along x axis is: 5N,15N,7N,10N.

    Please help me in this problem as it seems incomplete to me..
    F=FXCOS@,F=FYSIN@...dont know the angle as well.. The answer is 15N..

    Yeah, the question seems ill-posed. Are you sure this is the exact wording? Because, if you just say, "a force of 5 N acts along the y-axis", I interpret that to mean that this force acts entirely along the y-axis and has NO x-component.

    yes, this is the exact wording of the question...!
    is there any possibility to get 15N by amend this question a little?

    Not really, when the force itself is smaller than the component :uhh: You'd have to change the numbers as well as direction.
