1btw bhaiya,, i still din get this widout pseudo force...
will u give the full solution plz?
I personally dont like pseudo force.. (Used to love it when I was in class xi) but when i came to class xii.. i started to hate it..
Yeah there are some problems which are solved in a flash by using pseudo force.. but there are some where u will get confused a lot!
So giving a simple problem.. and want to see if u can solve it without pseudo force...
The Lift is falling down with accleleariton A

UP 0 DOWN 0 1 8

1here except pseudom force we have to take acceleration w.r.t. ground frame, i.e. a-A and a+A.
62ith power u are right.. whoever told me the solution privately have used pseudo force.. (even without knowing that they were!)
162The only reason is incorrect constraint equation....
Could you try to write them?
1T-Mg=-Ma ---1
T-mg=ma ----2
now we get a from here...
since the lift is fallinf down with A...
acc of M is a-A ... and the other one a+A.
1let the system fall with an acceleration a, and inside the elevator let the accn of system be A , thus assuming M>m , we get acn of M = a+A and accn of m =a-A , rihgt?
