Normal force in circular motion, is my work correct

  1. Nov 12, 2008 #1
    1. The problem statement, all variables and given/known data
    If:
    weight = m
    speed = v
    angle = theta
    radius = r

    Write an algebric expression that is equal to the Normal force


    2. Relevant equations
    F = ma
    acentr. = v2/r

    3. The attempt at a solution
    N -mgcos(theta) = m v2/r
    N = m v2/r +mgcos(theta)

    correct?
