Homework Help: Concept of pseudo force

  1. Oct 12, 2011 #1
    1. The problem statement, all variables and given/known data

    a block of mass m is resting on a wedge of angle θ as shown in fig. the wedge is given an accn. a towards left.what is the minimum value of a due to an external agent for which the mass will fall freely?

    2. Relevant equations

    N+m(asinθ) = 0.(N is the normal force)

    3. The attempt at a solution
    we draw the fbd of the mass m. we get the given equation.but without the mass of the wedge i cannot proceed. still my work is given in the adjacent image.
