Jupiter has about 300 times the mass of Earth and about ten times Earth's radius Estimate the size of g...

Question

on the surface of Jupiter?

Answer 1

g = GM/R^2, where g = acceleration due to gravity at surface of planet (or where a space traveler positions himself if there is no hard surface), G = Newton's gravitational constant, M = mass of planet (or that part of it below the space traveler).

Taking ratios, G drops out,
gj/ge = (Mj / Me) / ( [Rj / Re ]^2) = (300) / ( [10]^2)

gj/ge = 300/100 = 3

Acceleration of gravity (and hence force of gravity) at nominal surface of Jupiter is 3 times that felt on earth.

Answer 2

Jupiter has no surface its a gas giant composed mainly of methane .

Answer 3

g = GM/R^2
g(J)/g(E) = (M(J)/M(E))(R(E)^2/R^J)^2)
g(J)/g(E) ≈ (300/1)(1/10^2) ≈ 3.0
