The value of acceleration due to gravity is
maximum at poles and minimum at the equator
.
Where the value of g is maximum?
The value of G is maximum at
the poles
. This is due to the closeness between the poles and the center of the earth.
Where is G minimum on the earth?
Mount Nevado Huascarán in Peru
has the lowest gravitational acceleration, at 9.7639 m/s
2
, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s
2
. “Nevado was a bit surprising because it is about 1000 kilometres south of the equator,” says Hirt.
What is value of g?
In the first equation above, g is referred to as the acceleration of gravity. Its value is
9.8 m/s
2
on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s
2
.
Where is the value of g 0?
Answer: Acceleration due to the earth's gravity is zero
at the centre of the Earth
because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull.

Which country has lowest gravity?
Sri Lanka
has the lowest gravity on Earth.
What is value of g at equator?
Using Newton's law of gravity, we find that the force of earth's gravity on your body at the equator is
9.798 m/s
2
times the mass of your body
, whereas at the poles it is 9.863 m/s
2
times the mass of your body. The earth's centrifugal force also varies with latitude.
How is G calculated?
The
acceleration g=F/m
1
due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s
– 2
.
What is value of G Class 9?
➡️The value of g is
9.8 m/s^2
.
What does G in physics stand for?
The
universal gravitational constant
(G) relates the magnitude of the gravitational attractive force between two bodies to their masses and the distance between them. Its value is extremely difficult to measure experimentally.
At what height is g 0?
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.)
At what height g is zero?
Result: From the above calculation we can say that
at a height equal to half of the radius of the earth
the acceleration due to gravity becomes zero.
Why is g at center of Earth zero?
At the centre of Earth,
force due to any portion of the Earth at the centre will be cancelled due to the portion opposite to it
. Thus, the gravitational force at the centre on any body will be 0. Since, from Newton's law, we know F= mg. Since, mass m of an object can never be 0.
Why is value of g minimum at equator?
The value of ‘g' is minimum at the equator
because Earth is not a perfect sphere. Its radius is maximum at the equator
. Hence according to equation g = GM/R
2
, the equator is the place where g will be minimum.
At what points value of g is maximum and minimum on the surface of Earth?
Find the difference in the maximum and minimum value of g on the surface of the earth. Thus, acceleration due to gravity
is maximum at poles
. Thus, acceleration due to gravity is minimum at the equator.
