At what height the value of g becomes zero?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s−2 per 3,200 km.)

Where is the value of g 0 on earth?

the center of the Earth
So, acceleration due to gravity is zero at the center of the Earth. Consider a test mass (m) taken to a distance (d) below the earth’s surface, the acceleration due to gravity that point (gd) is obtained by taking the value of g in terms of density. Hence g=0 at the center of the earth.

At what height above the surface of earth is the value of g decreases by 1\%?

Thus at a height, h=0⋅005RE the acceleration due to gravity reduces by 1\%.

At what height from the surface of earth the value of g is half?

If we use 6,371 km as Earth’s radius, the distance above the surface where gravitational acceleration is halved would be 2,639 km.

Is gravity zero at the center of the Earth?

If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!). If the earth were about 36,000 km in diameter with the same mass and length-of-day then the gravity at the equator would be zero.

What is value of g at the Centre of Earth?

The value of g at the centre of the earth is zero.

What is value of G and g at the Centre of Earth?

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

At which height from the Earth surface does the acceleration due to gravity decrease by 75\% of its value at Earth surface?

Thus, at the height of 6400 km the acceleration due to gravity will decrease by 75\% of it’s value at the earth’s surface.

At what height from the surface of earth will the value of g be reduced by 36?

At what height from the surface of earth will the value of g be reduced by 36\% from the value on the surface? Take radius of earth R = 6400 km. Since the acceleration due to gravity reduces by 36\% the value of acceleration due to gravity there is 100-36=64\%.

At what height from the surface of earth the value of g will be I ½ II ¼ its value at earths surface radius of Earth 6400 km?

∴ At a height of 2649.6 km from the Earth’s surface, the acceleration due to gravity will be half its value on the surface.

What is the percentage of G at 800km above the earth surface?

Thus, at 800kmabove earth surface gbecomes 75\%of its value on earth surface. Was this answer helpful? 0 0 Similar questions Earth binds the atmosphere because of Hard View solution

What happens to acceleration due to gravity at 800 km above surface?

At which height from the earth’s surface, acceleration due to gravity is decreased by 75 \% of its value at earth’s surface. At which height from the earth’s surface, acceleration due to gravity is decreased by 75\% of its value at earth’s surface. Thus, at 800 km above earth surface g becomes 75\% of its value on earth surface.

How is the variation of G with height or depth shown?

The variation of g with height or depth ( r) is shown correctly by the graph in figure (where R is radius of the earth). 1. The gravitational force exerted by the sun on the moon is greater than the gravitational force exerted by the earth on the moon. 2. A heavy body falls at a faster rate than a light body in vacuum.

What is the altitude of the Earth at the square root 2?

Take the square root of 2 to find r = 1.414 times the radius of the Earth, or 9.05 million meters. That is an altitude of 2.65 million meters, or 2650 km (9.05 x 10^6 meters – 6.4 x 10^6 meters). , M.Sc. Retired as Head of Department of Physics.
