Question

A balloon filled with hydrogen is placed on the moon .The value of on moon is 1/6 that of earth then it will??
(a)remain stationary (b)fall with a=6 x 9.8 m/s^2  (c) fall with a=9.8/6   (d)rise with a 9.8/6

anonymous · Answer

Fall with a=9.8/6, because there's no air to be buoyant in on the moon. XD

??are u sure??how can it fall??i think it will get escape velocity and rise

nottim · Answer

Well, the Moon's got some gravity too, no?

nottim · Answer

And hydrogen can't float on "nothing".

anonymous · Answer

Yes, Newton's law of gravitation F=GmM/r^2, means that the moon, as a mass, will exert force. But there's no force from buoyancy acting on that balloon since there's no atmosphere.

Physics, yo.

aravindg · Answer

but thats very low .u see moon has g value 1/6 of that on earth .thats why it dont have atmosphere..

nottim · Answer

I don't understand the different between b and c...

nottim · Answer

Cause im stupid.

aravindg · Answer

lol

aravindg · Answer

y cant it rise/?it can easily get escape velocity

anonymous · Answer

@AravindG It's very low but there's no other force acting on it.
