the tension should be zero since the acc. of both the blocks will be same (even without the string)

2mMgsin@/(M+m)

How can the tension is zero?

V can even solve dis by eqns. of motion....
Mgsin@ - T - uMgcos@ = Ma ------ 1
mgsin@ + T - umgcos@ = ma ---- 2

Adding 1 nd 2
gsin@(M + m) - ugcos@(M+m) = (m+M)a
so,
a = gsin@ - ugcos@
Substituting in 1....

T = 0..
