If Earth were twice as massive but remained the same size what would happen to the value of G?

g is directly proptional to mass of earth. if the mass of eath will be increase mass of g will be also increase.If the mass of earth will be decrease the mass of g will bi also decrease.If the mass of earth will increase four times then the mass of g will be also increase four times.
G is a gravitational contant.it remain same throughout the universe
if the mass of earth will become four times,the value of G will not change it will remain the same as it is a constant.its value is 6.67x 10^-11 N-M^/KG

Why light and heavier objects when fall through vacuum move side by side?
Relevant formulae: weight = mass x gravity force = mass x acceleration (Newton's Second Law) Let's say, for the sake of argument, that one object has twice the mass of the other. For example, 2 kg versus 1 kg. The more massive object will be subject to twice the gravitational force - close to Earth's surface, that would be about 20 newton, compared to 10 newton for the less massive object. But the more massive object also has twice as much inertia; that is, twice the force divided by twice the mass will provide the same acceleration.
How would you present weight change if earth had twice the mass it does now?
If Earth had the same size but twice the mass you would weight twice as much
Near the Earth's surface the amount of mass an object has does not affect its acceleration due to gravity?
That is correct. Earth's gravity, often expressed as 9.8 meters per second square, can also be expressed as the equivalent 9.8 Newton per meter. That is, an object of twice the mass will feel twice the force of attraction from Earth. However, it will also have twice the inertia - it requires twice the force to give it a certain acceleration.

How is kinetic energy related to mass?
KE=0.5*m*v^2 Therefore the more massive an object, the greater it's kinetic energy is
What would happen if the sun was twice as massive?
if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000
This planet is more than twice as massive as all the other planets?
Earth
What would happen to the Earth's tides if the moon was twice the size as it is now?
What matters heres is the Moon's mass, as well as its distance. With a more massive Moon (and in the same orbit), the tides would of course be stronger.
if the earth had twice it’s present radius and twice it’s present mass, what would happen to your weight explain your answer?
i will be twice as heavy
If the Sun were replaced by a star with twice as much mass what would happen to the gravitational force between Earth and the Sun?
If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.
What would happen if earth began to rotate twice?
Actually I dont know, but I guess the rate of everything happeningnow would be twice as fast.
What connection between the mass of a planet and the number of moons it has?
There is no direct connection between the mass of a planet and the number of moons it has. Mars is less massive than Earth but has twice as many moons as does Earth. Jupiter is more massive than either Mars of Earth and has many more moons that either of them.

If the sun had twice as much diameter and mass what would happen to the gravitational force between Earth and the Sun?
Double
What would happen if the earth had twice as much oxygen?
If Earth had twice as much oxygen as it does, fires would start easier and burn hotter. Arthropods (insects, spiders and the like) could be a good deal larger than they are now.
What would happen if the sun was replaced by Sirius A?
Sirius A is about twice as massive as our sun, but has a surface temperature of around 10000 degrees Kelvin, compared with our suns surface temperature of around 5800 Kelvin. The Earth and all of the other planets would be a lot hotter if they remained at their current orbit, though the orbits would change as the gravitational pull of Sirius A would be greater. The water on earth would boil off and it would become a barren planet that could not support life. Even Mars may be too hot to support life if Sirius A were our star.
