Two bodies A and B of mass 100 g and 200 grespectively are dropped near the earth'ssurface. Let the accelaration of A and B be a,and a, respectively.(a) a = ar(b) a, <a,(c) a sa,(d) a, #az

Answer»

Force at work here (gravity) is also dependent on the mass

gravity acts on a body with mass m with

F=mgF=mg

you will plug this in to

F=maF=ma

and you get

ma=mgma=mg

a=ga=g

and this is true for all bodies no matter what the mass is. Since they are accelerated the same and start with the same initial conditions (at rest and dropped from a height h) they will hit the floor at the same time.

Hence,option (a) a₁=a₂ is correct.
