Geostationary and Polar Satellites

A satellite revolves in the geostationary orbit but in a direction east to west. The time interval between its successive passing about a point on the equator is 

When the period of rotation of a satellite from west to east is the same as that of the earth, then the relative velocity of a satellite is equal to

What is the time period of a satellite revolving in a geostationary orbit?

A geostationary satellite against gravity revolves around the earth from :-

The period of geostationary satellite is-

The orbit of a polar satellite is _________.

Polar satellites:

A synchronous satellite goes around the earth once in every $24\mathrm{ }\mathrm{h}.$ What is the radius of orbit of the synchronous satellite in terms of the earth's radius?
(Given: mass of the earth, $M_{\mathit{E}}=5.98\times {10}^{24}\mathrm{ }\mathrm{k}\mathrm{g}$ , radius of the earth, $R_{\mathit{E}}=6.37\times {10}^6\mathrm{ }\mathrm{m}$ and universal gravitational constant, $G=6.67\times {10}^{-11}\mathrm{N}\mathrm{ }{\mathrm{m}}^2\mathrm{ }\mathrm{k}{\mathrm{g}}^{-2}$)

A geostationary satellite orbits around the earth in a circular orbit of radius $36000 \mathrm{km}$. Then, the time period of a spy satellite orbiting a few hundred kilometres above the earth's surface $\left(R_{\mathrm{Earth}}=6400 \mathrm{km}\right)$ will approximately be :

A satellite of earth can move only in those orbits whose plane coincides with

A satellite appears to be at rest when seen from the equator. Its height from the earth's surface is nearly.  $g=9.8 \mathrm{m} {\mathrm{s}}^{-2}$

Given radius of Earth $R$ and length of a day $T$ the height of a geostationary satellite is [$G$-Gravitational constant. $M$-Mass of Earth]

Distance of geostationary satellite from the surface of earth radius $\left(R_e=6400 \mathrm{km}\right)$ in terms of $R_e$ is 

. _____ will finish the construction of the BeiDou-3 Navigation Satellite System (BDS-3), with another two geostationary orbit satellites to be launched before June 2020

Geostationary satellites are widely used for:

If a satellite has to orbit the earth in a circular path every $6 \mathrm{h}$, at what distance from the surface of the earth should be satellite placed (radius of earth, $R_{\mathrm{e}}=6400 \mathrm{km}$) (assume, $\frac{GM}{4{\pi }^2}=8.0\times {10}^{12} \mathrm{N} {\mathrm{m}}^{-2} {\mathrm{kg}}^{-1}$, where $G$ and $M$ are gravitational constant and mass of earth and ${10}^{1/3}=2.1$),

The orbit of a geostationary satellite is circular. The time period of satellite depends on,

$\mathrm{I})$ mass of the satellite.

$\mathrm{II})$ mass of the earth.

$\mathrm{III})$ radius of the orbit.

$\mathrm{IV})$ height of the satellite from the surface of the earth.

Which of the following option is correct?

A geo synchronous satellite is revolving around the earth. What will be its orbital radius? (Radius of the earth $6400 \mathrm{km}$)

If the time period of the satellite in geostationary orbit of planet $A$ is $T$ then its time period in geostationary orbit of planet $B$ is:

(Both the planets have same angular frequency of rotation)

A geo-stationary satellite is orbiting the Earth at a height of $6R$ above the surface of the earth, $R$ being the radius of the Earth. The time period of another satellite at a height of $2.5R$ from the surface of Earth is
