 P: 372 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 $$1.2m/s^2$$ 2. Relevant equations $$F_{net}=ma_{net}$$ 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, $$T-F_g-F=ma$$ $$a=1.2$$ 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 $$a_{net}=0$$.Now how is this possible?
