Q) Forces P, Q and R act on a particle at O in the plane of the coordinate axes Ox, Oy. Force P acts along Ox, Q acts along Oy, and R acts at an angle a with Ox, in the first quadrant. Calculate magnitude of the resultant force and angle it makes with Ox.
P = 3N, Q = 4N, R = 5N, a = 60 degrees
I would really like if someone can draw diagrams too, any help will be appreciated.
thx.
