What will be the value of g if we go a distance equal to diameter of earth from its surface?
9.8 m/s2
That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2….The Value of g Depends on Location.
| Location | Distance from Earth’s center (m) | Value of g (m/s2) |
|---|---|---|
| Earth’s surface | 6.38 x 106 m | 9.8 |
| 1000 km above surface | 7.38 x 106 m | 7.33 |
What is the distance from the Earth’s center to a point out side the earth where the gravitational acceleration due to the Earth is 1/16 of its value at the Earth’s surface?
The radius of the Earth is approximately 4000 miles. Gravity obeys an inverse square law, decreasing by the square of the distance from the centre. So the gravitational acceleration due to the Earth will be 124 th at a distance: √24⋅4000≈√25⋅4000=5⋅4000=20000 miles.
What happens to the value of g when we go away from earth?
This is the acceleration due to gravity at a height above the surface of the earth. Observing the above formula we can say that the value of g decreases with increase in height of an object and the value of g becomes zero at infinite distance from the earth.
What is the gravitational field at the surface of the earth due to the moon?
1.625 m/s2
The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6\% that on Earth’s surface or 0.166 ɡ….Gravitational field.

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G). The relation between G and g is not proportional.
At what distance from the center of Earth is?
The average distance to the centre of the Earth is 6,371 km or 3,959 miles. In other words, if you could dig a hole 6,371 km, you’d reach the center of the Earth. At this point you’d be in the Earth’s liquid metal core.
What is the distance from Earth to center of Earth?
6,371 kilometers
The distance to the center of the Earth is 6,371 kilometers (3,958 mi), the crust is 35 kilometers (21 mi) thick, the mantle is 2855km (1774 mi) thick — and get this: the deepest we have ever drilled is the Kola Superdeep Borehole, which is just 12km deep.
How does the value of g change on moving away from the surface of the earth and towards the Centre of the earth?
Answer: Yes, for both the cases it does change. The value of ‘g’, i.e., acceleration due to gravity does not remain the same on all places of the surface of the earth. It can be easily made out that the value of ‘g’ varies on the basis of altitude.
What is the gravitational field at the surface of the earth due to the sun?
The force of gravity on earth due to the sun is 3.6 x 10^22N.
