Best ResponseYou've already chosen the best response.0i want to give you a quick help. if elevator is ascending then always add g and acceleration of elevator. if elevator is ascending then always subtract g and acceleration of elevator.

Best ResponseYou've already chosen the best response.3If the lift is ascending at a rate of g/3, the mass of the pendulum experiences a net acceleration, a new apparent gravitational force, \( g' \), of \[g' = g + g/3 = \frac{4}{3}g \] You know \[ T = 2\pi \sqrt{L/g} \] Hence what you have to do is find the period \( T ' = 2\pi \sqrt{L/g'} \) in terms of \( T \).

Best ResponseYou've already chosen the best response.0but here g'=2g/3 becoz apparent acc= a+g/3

Best ResponseYou've already chosen the best response.3Think about it. When a lift takes off upwards, i.e., accelerating upwards, you feel heavier, not lighter. Conversely when it is accelerating downwards you feel lighter. Therefore we need to add g/3 to g, not subtract it.

Best ResponseYou've already chosen the best response.0i agree but not g we will add a we were taught in upwards a=g+a in downwards a=ga

Best ResponseYou've already chosen the best response.0okay if you want to through fundamentals then forget everything(formulas n tricks) and think of tension. make a free body diagram of the pendulumdw:1327858223624:dw Fnet = T  mg Fnet = ma = T  mg m(g/3) = Tmg T=4mg/3 since this tension decides the apparent weight of the bob, and hence the apparent "g".. so apparent g= 4g/3 now,\[T= 2\pi \sqrt{l/g(apparent)}\] therefore,\[T' = \sqrt{3}/2T\]
