How much is the radius of the Earth at the equator greater than the radius at the poles?
(21 KM) The Earth is not a perfect sphere; it is an oblate spheroid,meaning it bulges at the equator and is flattened at the poles.
The equatorial radius of the Earth is approximately $6378 \; km$.
The polar radius of the Earth is approximately $6357 \; km$.
The difference between the equatorial radius and the polar radius is $6378 \; km - 6357 \; km = 21 \; km$.
The equatorial radius of the Earth is approximately $6378 \; km$.
The polar radius of the Earth is approximately $6357 \; km$.
The difference between the equatorial radius and the polar radius is $6378 \; km - 6357 \; km = 21 \; km$.

View SolutionThe depth $d$ at which the value of acceleration due to gravity becomes $\frac{1}{n-1}$ times the value at the earth's surface is ($R=$ radius of the earth).
The depth $d$ at which the acceleration due to gravity becomes $\frac{g}{n}$ is (where $R$ is the radius of the Earth,$g$ is the acceleration due to gravity at the surface,and $n$ is an integer).
The density of a new planet is twice that of earth. The acceleration due to gravity at the surface of the planet is equal to that at the surface of earth. If $R$ is the radius of earth,then the radius of the planet would be
