The ratio of mean distances of three planets from the sun are `0.5 : 1: 1:5`, then the square of time periods are in the ratio of

The period T and mean distance R of a planet from the sun are related by

The ratio of the distances of two planets from the sun is 1.38. The ratio of their period of revolution around the sun is

The ratio of the distance of two planets from the sun is 1:2 . Then ratio of their priods of revolutions is

The ratio of the distance of two planets from the sun is 1:2. The ratio of their periods of revolution is

The distances of two planets from the sun are 10^12 m and 10^10 m respectively.The ratio of the time periods of these planets is

The distance of two planets from the sun are 10^(13) and 10^(12) m respectively. The ratio of the periods of the planet is

The distance of two planets from the sun are 10^(13) and 10^(12) m respectively. The ratio of the periods of the planet is

The distance of the two planets from the Sun are 10^(13)m and 10^(12) m , respectively. Find the ratio of time periods of the two planets.
