Dear Souvik,

Acceleration of A and B along their contact surface must be same for them to remain in contact 

=> a1 cos θ = a2 sin θ // constraint relation

From FBD of A you will get
N sin θ = M a1

From FBD of B you will get 
Mg - N cos θ = M a2

Solving these you will get your answer


Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly. All the best.Regards,
