11sorry guys i have thought something wrong
A MAN IS STANDING ON A WEIGHING MACHINE WHICH READS ZERO.HOW DO WE KNOW IF THE MAN IS INSIDE A FREELY FALLING LIFT OR IN A SATELITE.

11to know wheather he is in lift or satelite,if he releases a ball from rest if the ball moves downward with respect to him then he must be inside the lift.otherwise he is in satelite .
19supposing that the man is absolutely alone, there is no way to differentiate !!!
49no swaraj he cannot differentiate in any way, unless the lift hits ground and he gets a leg fracture or spondilitis out of it:P
and swaraj how come the relative accn is 2g???the r being attracted in same direction by earth and relative accn is g-g=2g.....
1The man won't be able to differetiate between the two positions. A satellite is in a weightless state and on earth again, in a freely falling state . Hence in both the situations the Normal reaction will be 0 and the man won't be able to identify his position...Let him go to hell if he does.
(Now only his gf from outside will be able to tell him that he's going to die in any case..otherwise he won't know. :P lolzzzzzzzz)
1MY PHYSICS TEACHER SAID THAT IT CANNOT BE DEDUCED BY ANY EXPERIMENT,SO IT MUST BE SO.
62yes he is right.. but the reason should not be that the "physics teacher said so " :D
1nishant bhaiya..dont u think wat swaraj has said is quite viable....the ball being released????
66In fact, Swaraj is not entirely wrong. In fact, we CAN differentiate between the two situations.
Consider that the lift falls freely in a shaft that is very deep. If the man stands on a weighing machine, the reading is obviously zero. However, suppose that the man has two balls; one is each of his outstretched hands. If he release them, the ball would simply float beside him. But if the fall takes a long time, then he would actually see the balls slowly moving towards each other. The reason is again quite obvious. The balls (and of course the man as well) are actually falling towards the center of the Earth along radial paths. And these radial paths are converging slowly. So the two balls seem to attract each other.
This phenomena won't happen in a spaceship which is drifting with a constant velocity.
That means the two situation can be differentiated.
49Genius!!!!!!!!!!!!!!!!!!!!!!!![1][1][1]awesome...............thats y anant sir is anant sir......
1Kudos to Anant Sir !!!!! Great deduction.......and a beautiful solution.
1Anant Sir has perhaps used the "Principle of Curvature of Space".....am i right Sir ??
