6.2 Gravitation - Quiz - Baldeep Sawhney | Biblioteka

There is a proposal to place a satellite in orbit around planet Mars.

The satellite is to have an orbital time T equal to the length of a day on Mars.

It can be shown that T²= kR³

whereR is the orbital radius of the satellite and k is a constant.

The ratio :

distance of Mars from the Sun

________________________________ = 1.5

distance of Earth from the Sun
