(adsbygoogle = window.adsbygoogle || []).push({}); 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.
