What is the range from the Earth's surface ,where an artificial satellite, to detect a precise latitude and longitude of a place, should revolve?

A body of mass m rises to a height h=R//5 from the earth's surface where R is earth's radius. If g is acceleration due to gravity at the earth's surface, the increase in potential energy is

The broadcast signals that originate from a radio station are sent to an artificial satellite for redistribution to other locations. Name the orbit where such satellites should be placed and the launch vehicle used.

The ratio of binding energy of a satellite at rest on earth's surface to the binding energy of a satellite of same mass revolving around of the earth at a height h above the earth's surface is (R = radius of the earth).

The gravitational force due to the earth also acts on the moon because of which it revolves around the earth. Similar situation exists for the artificial satellites orbiting the earth. The moon and the artificial satellites orbit the earth. The earth attracts them towards itself but unlike the falling apple,they do not fall on the earth, why?

The height of a communication satellite from the earth's surface is about

In a surface tension experiment with a capillary tube water rises upto 0.1 m . If the same experiment is repeated in an artificial satellite, which is revolving around the earth , water will rise in the capillary tube upto a height of :

A satellite is revolving in a circular orbit at a height 'h' from the earth's surface (radius of earth R, h <

The rotation period of an earth satellite close to the surface of the earth is 83 minutes. The time period of another earth satellite in an orbit at a distance of three earth radii from its surface will be

The escape velocity of a body from the surface of the earth is 11.2 km//s . If a satellite were to orbit close to the earth's surface, what would be its critical velocity?
