    An object in the plane is subjected to two forces. The first F1 has magnitude 5N and
    direction pie/4 to the left of the positive y-axis. The second F2 has magnitude 20N. If
    the resultant force on the object has direction pie/4 to the right of the positive y-axis,
    find the direction of F2 (in radians, to 3dp).

    Can anyone help please?

    hmm i think this question tells u that the resultan force and F1 has a pi/2 angle between them..that means you can form a nice triangle and solve it... my answer is 0.54 radians to the right of the positive y achsis... can somebody check this answer?

    To find the correct answer, we must ask the right question. What is 'pie'?
