What is acceleration due to gravity on surface of planet that has radius half that of earth and same average density as earth?

g=Gx4(pi)/3xr3x(rho)/r2=Gx4x(pi)x(rho)xr/3
Now if the radius is halved then acceleration will also halve.

What is value of average acceleration for gravity?
9.81 m/s^2 on the earth's surface
What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
What is the force of acceleration do to gravity on Earth?
The acceleration due to gravity on or near the Earth's surface is about 9.81 meters per second2 . The forces of gravity between the Earth and a mass on or near the surface are 9.81 newtons per kilogram in each direction.
What is the gravitational acceleration of an object on the surface of the earth?
At or near the surface of the earth, the acceleration due to gravity is 32 feet per second per second
What is value of average acceleration for gravity?
9.81 m/s^2 on the earth's surface
Why will a dense area of rock under the surface increase the local strength of gravity?
density is directly proportional to the mass density = mass / volume more density, then more mass and more mass, more gravity, as gravity force = mass x gravity acceleration.
What is makemakes gravity compared to earths gravity?
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
How does the force due to gravity on Mars compare to the force due to gravity on Earth?
The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.
What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
How is gravity affected if mass is changed?
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
What is the percentage of the acceleration due to gravity between the surface?
its 13.6
What restriction exist in using 9.81 N per kg as the proportionality constant for determining weight?
It is an approximate average value for acceleration due to gravity on the surface of the earth. It is affected by altitude, the density of the material near the surface from place to place. And of course, it is totally useless in space, on the moon or Mars.
The acceleration of gravity on the surface of a planet will effect a person or objects?
The acceleration affects the weight of the person and object
The acceleration of gravity on the surface of a planet will effect a person's or object's what?
weight
What is the force of acceleration do to gravity on Earth?
The acceleration due to gravity on or near the Earth's surface is about 9.81 meters per second2 . The forces of gravity between the Earth and a mass on or near the surface are 9.81 newtons per kilogram in each direction.
