Homework Statement
2. The attempt at a solution
Let rightward acceleration of the block (A+B) be $$a$$.
Let downward acceleration of block (A) be $$a'$$ down.
For block A:
$$mg-T=ma'$$
$$N+ma=0$$
For block B:
$$T+N=Ma$$
On solving $$N=-\dfrac{m^2g}{M+2m}$$ by taking $$a=a'$$.But that is wrong answer.
Where did I go wrong?
