We would require a place with no resisting force whatsoever, like on earth we have air resistance etc
Then, if we drop any two objects, they would reach the ground at the same time. This is because,
F = ma = mg
F(by which an object is attracted toward a body) = (G*M*m)/d²
⇒f (gravity) = mg = (G*M*m)/d²
⇒gravity = G*M/d²
This shows that gravity i.e. acceleration due to gravity is dependent only on mass of the planet and it’s distance from the surface or radius of the planet
Also, gravity is independent of the object’s mass.......only on an ideal planet with no resistance!
