1. The problem statement, all variables and given/known data

A block of mass m is placed on an inclined plane. the angle of inclination is θ. now i want to understand in which direction (horizontal) the plane should be accelerated so that the block on it doesn't move.

2. Relevant equations

3. The attempt at a solution

now all the time the block has a downwards acceleration because of one of the components of its weight which is mgsinθ. now the plane should be moved in such a way that a component of the force exerted on the plane should nullify mgsinθ.

If a force F is applied on the plane towards the inclined surface (parallel to base) then it has two components , Fcosθ (parallel to the the surface) & Fsinθ (against the weight). now it's actually increasing the accln of the block.

2ndly, if i want to find the accln (a) of the plane then i have to use then force F which is Ma (M is the mass of the plane not the block, which is not given). then i can i find a.

am i thinking right..or not...i think i am not getting the concept of it...plz help me...
