    vectors in circular motion.

    vectors in circular motion.-screenshot-30-.png
    W= -mg sinθ er - mg cosθ eθ.
    N= -|N| er
    F=ma= m(-R
    dotθ2 er + R doubledotθ eθ)
    resolving in er-direction,

    -m
    Rdotθ2 = -|N|-mg sinθ
    mRdotθ2 = |N|+ mg sinθ

    am i right doing this?

    correct ... net radial force would be the sum of the normal reaction force and the radial component of weight.
