What would happen to your weight on Earth if the radius of the earth tripled but its mass stayed the same?

Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.

What will be the value of g if mass of Earth becomes four times?

So, if the mass alone is increased by four times (4M) the value of ‘g’ will become 4GM/r^2.

What planet is 4 times the mass of Earth?

Although Uranus, discovered in 1781, is only four times the physical size of Earth, it is significantly more massive, weighing in at 86 septillion kilograms (just under one trillion trillion trillion).

What would happen to gravity if the Earth’s radius doubled?

If we assume that the density of the Earth stays the same, then doubling the radius increases the planet’s mass eight-fold. Surface gravity is now doubled, so most plants and trees promptly fall over.

What would happen to weight if the mass was doubled?

The perceived weight of an object is directly proportional to its mass, which means that if the mass doubles, then the weight doubles.

What would happen if the Earth’s mass doubled?

If Earth’s mass doubled then the acceleration due to gravity, which we normally feel as 9.81 m/s, would also double. So you can expect an acceleration of about 19.62 m/. Do keep in mind that this assumes that the volume of Earth would not change. So it’s likely that everybody and everything will die.

What happens to the value of G as we go towards the Centre of the earth?

As we go inside the earth, our distance from the centre of the earth decreases and no longer remains equal to the radius of the earth (R). Due to combined result of a change in R and M, value of g decreases as we go deep inside the earth.

What will happen to the value of G if the size of the two objects is increased?

Explanation:The value of G is a universal constant and it remains constant throughout the universe. The change in the masses of the objects won’t affect it’s value.

Is Uranus 4 times bigger than Earth?

With a radius of 15,759.2 miles (25,362 kilometers), Uranus is 4 times wider than Earth. If Earth was the size of a nickel, Uranus would be about as big as a softball. From an average distance of 1.8 billion miles (2.9 billion kilometers), Uranus is 19.8 astronomical units away from the Sun.

What are the mass and radius of this planet?

We know that the acceleration due to gravity is equal to 9.8 m/s2, the Gravitational constant (G) is 6.673 × 10−11 Nm2/kg2, the radius of the Earth is 6.37 × 106 m, and mass cancels out. When we rearrange the equation and plug all the numbers in, we find that the mass of the Earth is 5.96 × 1024 kg.

What will happen if the size of the Earth is two times bigger than its original size?

If Earth were twice its size, you’d be heavier, because the force of gravity increases as the planet’s density and radius increase. The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth’s surface would increase.

What if the Earth were twice as Big?

Part 7: What if Earth were twice as big? If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong.

Why is the mass of the Earth directly proportional to radius?

Well the mass of the earth is directly proportional to its gravity and the radius is inversely proportional to its gravity. It means the more the mass of a heavenly body the more gravitaional force its exerts thus you’ll be about 2.5 times as heavy you are here in Jupiter.

Is the Earth getting bigger or smaller?

And that carbon dioxide came from somewhere else on Earth. None of these processes actually makes the Earth bigger or smaller — no mass is being created or destroyed. Atoms are just getting moved from one place to another. But Earth’s size isn’t quite constant.

What would happen to your weight if Earth’s mass was reduced?

For your question, the only thing changing is the mass of the Earth. The weight and mass of Earth are directly proportional if nothing else changes. This means that if the mass of Earth tripled, your weight would triple. If the mass of Earth was reduced to half, your weight would reduce to half. Weight is also known as the force of gravity.
