Answer the following questions : Let the period of revolution of a planet at a distance R from a star be T. Prove that if it was at a distance of 2R from the star, its period of revolution will be sqrt8T .

Let the period of revolution of a planet at a distance R from a star be T. Prove that if it was at a distance of 2R from the star, its period of revolution will be sqrt(8)T .

Let the period of revolution of a planet at a distance 2R from a star be T. Prove that if it was at a distance of 8R from the star, its period of revolution will be 8T.

According to Kepler, the period of revolution of a planet ( T ) and its mean distance from the sun ( r ) are related by the equation

The period of revolution of planet A round from the sun is 8 times that of B. The distance of A from the sun is how many times greater then tht of B from the sun ?

If T is the time period of revolution of a satellite, then K.E. is proportional to

If the distance between the earth and sun becomes 1/4 ^(th) , then its period of revolution around the sun will become

The magnetic field at a distance r from a long wire carryimg current I is 0.4 T. The magnetic field at a distance 2r is

The mass density of a spherical galaxy varies as K/r over a large distance 'r' from its centre. In that region, a small star is in a circular orbit of radius R. Then the period of revolution, T depends on R as:

Imagine a light planet revolving around a very massive star in a circular orbit of radius R with a period of revolution T. if the gravitational force of attraction between the planet and the star is proportational to R^(-5//2) , then (a) T^(2) is proportional to R^(2) (b) T^(2) is proportional to R^(7//2) (c) T^(2) is proportional to R^(3//3) (d) T^(2) is proportional to R^(3.75) .
