A block of mass m is placed on a smooth inclined wedge $A BC$ of inclination $θ$ as shown in the figure. The wedge is given an acceleration 'a' towards the right. The relation between a and $θ$ for the block to remain stationary on the wedge is

Options:

Answer:

Solution:

Let the mass of block is m. It will remains stationary if forces acting on it are in equilibrium. i.e., $ma cos θ = m g sin θ$ $\Rightarrow a = g tan θ$
Here $ma =$ Pseudo force on block, $mg =$ weight
