Where is gravity maximum pole or equator?
Note: The acceleration due to gravity is maximum at poles because the poles are near to the centre of mass of the earth. And the equator is somewhere far away from the centre of mass of the earth. And also, the acceleration due to gravity is slightly affected by the centrifugal force due to the rotation of the earth.
Where gravity is maximum?
poles
The correct answer is At poles. The result is that the weight of a body on the Earth’s surface increases slightly as it moves away from the equator and toward the poles. This is because the Earth’s gravitational force is slightly less at the equator than at the poles.
What is the value of gravity at poles?
about 9.832 m/s2
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5\% more at the poles than at the Equator.
Why is weight maximum at pole or equator?
As the distance of the pole is less than the distance of the equator from the center of the earth, the force of attraction is higher on the body at poles than at the equator. Hence the weight of a body is greater at pole than at the equator.
How is gravity more at the poles?
The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth. Therefore the acceleration due to gravity is greater at the poles than at the equator.
What is the value of gravity at equator?
9.798 m/s2
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/s2 times the mass of your body, whereas at the poles it is 9.863 m/s2 times the mass of your body. The earth’s centrifugal force also varies with latitude.
Why gravity is more at pole than equator Class 9?
It is flattened at the poles and bulged at the equator. The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth. Therefore the acceleration due to gravity is greater at the poles than at the equator.
Where is value of G minimum at poles or 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/R2 , the equator is the place where g will be minimum. Why the value of g is more at the poles than at the equator of the earth?
Which pole has more gravity?
The Earth’s gravity is stronger at the poles than the equator for two reasons: The centrifugal “force” cancels out the gravity minimally, more so at the equator than at the poles. The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
Why the value of g is greater at poles than the equator?
Earth is not a perfect sphere. The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth. Therefore the acceleration due to gravity is greater at the poles than at the equator.
