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.
