The total number of planets of Sun can be denoted by the variable n.

If n(A)=4 ,then total number of reflexive relations that can be defined on the set A is

The four planets closest to the Sun are called

The torque on a planet about the centre of sun is

The variation in the speed of the planet in their orbits about the sun can be explained on the basic of the conservation of :-

The time period of revolution of a planet A around the sun is 27 time that of another planet B .The distance of planet A from sun is how many times greater than that of the planet B from the sun?

The distance of a planet from the sun is 5 times the distance between the earth and the sun. The time period of the planet is

A planet is revolving around the sun. its distance from the sun at apogee is r_(A) and that at perigee is r_(p) . The masses of planet and sun are 'm' and M respectively, V_(A) is the velocity of planet at apogee and V_(P) is at perigee respectively and T is the time period of revolution of planet around the sun, then identify the wrong answer.
