QUESTION: 2

Aman stands on a weighingmachine kept inside a lift. Initially the lift is ascending with the acceleration ‘a’ due to which the reading is W. Now the lift decends with the same accleration and reading is 10 % of initial. Find the acceleration of lift ?

Solution: During ascend relative acceleration = g+a during descent relative acceleration =g-a according to question the descending acceleration is 10%of ascending acceleration. so if we solve it then (g+a)/10=g-a hence if you solve it you get a=9g/11 .
