Question

Is there a situation in which a planet that has twice the mass of the Earth can have the same free-fall acceleration as Earth (~9.8m/s^2)?

Answer 1

wtf sort of questions is this, free fall acceleration is relative to the distance you are away from the planet. So yes, you could be further away from the planet of larger mass, not double the distance though, it is an exponential relationship between distance and force. But this is a retarded question anyway.

Answer 2

hey man, i didn't make up the question. i guess it has more to do with the radius. if that planet's radius is √2*Radius of earth but twice earth mass would the acceleration remain -9.8? if the gravitational constant of the solar system was halved, would it remain -9.8? i agree it's a dumb question the way it's worded.

Answer 3

Yeah just look at the equation g = GM/r^2. Looks like you have the right idea

Answer 4

thanks :) appreciate the help

Answer 5

Looks to me like you didnt need help haha no problem though
