1. The problem statement, all variables and given/known data
A block of mass 50g is suspended from the ceiling of an elevator.Find the tension in the string if the elevator goes up with an acceleration of [tex]1.2m/s^2[/tex]
2. Relevant equations
[tex]F_{net}=ma_{net}[/tex]
3. The attempt at a solution
I have reached here:...but with this i dont get the books answer...The book takes net acceleration to be 0
If F be the pseudo force...then,
[tex]T-F_g-F=ma[/tex]
[tex]a=1.2[/tex]
So solving this i get an answer that differs from the one given in a problem book...that is 55N(the book's ans)
Ive realized that we get 55N if we take [tex]a_{net}=0[/tex].Now how is this possible?
