A block of mass m is placed on a smooth inclined wedge ABC 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 :-

Neet 2018 NLM & Friction q 2 I told earlier during discussion of qus of year 2004 that you should remember results of such kind of qus(as we had similar qus in year 2004)because this type of qus acts as standard qus . They may come in some different form or they can be a part of a long qus. Either way , you will be get benefited as here in this case . qus is asking about relation between acceleration and angle of inclination (In 2004 normal reaction force was asked)After watching first hint video Fotu Banao you can understand that gravitational pull down the incline is going to be balanced by component of Pseudo along the incline upwards. By equating them , we will get the desired answer.
