physics (vector)

posted by .

the force f1 and f2 are acting on a body one force is double that of the other force and the resultant is equal to the greater force.then the angle between two forceis what. How?

  • physics (vector) -

    Use the law of cosines, and solve for the cosine.

  • physics (vector) -

    what is force

  • physics (vector) -

    F1 = F2*Cos A.
    Replace F2 with 2F1:
    F1 = 2F1*Cos A
    Divide both sides by 2F1:
    Cos A = 0.50.
    A = 60o.
