What is the acceleration due to gravity on the surface of a planet that has half the mass of Earth and half the radius of Earth?

4m/s2
4m/s2.

What will be the acceleration due to gravity in a planet having half the radius of Earth but twice as massive than Earth?

The force of gravity on Earth is roughly 9.8 m/s^2 but on this other planet, it would be: 9.8(m/s^2)*2*4=78.4m/s^2. Suppose a planet exists whose mass and radius both are half those of the earth.

What is the value of gravitational acceleration on the planet which has twice the mass and twice the radius of the earth?

9.81 m/s^2 = 39.24 m/s^2).

How do you calculate the acceleration due to gravity of a planet?

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.

How does the acceleration due to gravity at the surface of a planet change if the planet’s radius is doubled?

If the mass of the Earth were doubled and the radius of the earth were doubled, then the two changes would offset each other and the acceleration of gravity on its surface would still be approximately 10 m/s2.

How does the acceleration due to gravity at the surface of a planet change if the planet’s mass is doubled?

If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

When the radius and mass of a planet both are reduced to half and the mass of an object is also reduced to half then the value of g *?

Hence, the correct answer is that If the radius of the earth is reduced to half of its present value, with no change in the mass, the acceleration due to gravity will become Four times to that of the original value which is option B.

What planet has half the gravity of Earth?

Jupiter
Jupiter has more mass than Earth so its gravity is two and a half times greater. Pluto is much smaller than Earth and so the force of gravity on Pluto is weaker than it is on Earth. This clip could be used when learning about the constant force of gravity and how it differs from one planet to another.

What would the acceleration due to gravity be on the surface of a planet with the same radius but twice the mass of the Earth?

It should be g=GM/r^2, where r^2 means the radius squared. After correcting the formula you can calculate that the gravitational acceleration on the surface of a planet with a mass twice that of earth’s mass and with radius twice earth’s radius will be half that on earth, namely 4.9 m/s^2 (9.8/2 m/s^2).

What happens to acceleration due to gravity on a planet as it becomes larger?

But on a bigger planet than Earth, the acceleration of gravity would be bigger, and you’d fall faster.
