The sun has a mass of `2 xx10^(30) kg` and Mars has a mass of `6xx10^(23) kg`. How does the acceleration of the sun due to Mars compare to the acceleration of Mars due to the sun ?

A planet has a mass of 2.4xx10^(26) kg with a diameter of 3xx10^(8) m. What will be the acceleration due to gravity on that planet ?

Given that mass of sun is 2 xx10^(30) kg and radius of sun is 7 xx10^(8) m . In what range do you expect the mass density of the sum to be ? Is it in the range of density of solid or liquid or gas ? Explain.

Mass of mars is 6.42xx10^(29) kg and mass of the sun is 1.99xx10^(30)kg . What is the total mass?

The mass of sun is 2xx10^(30) kg and mass of earth is 6xx10^(24) kg. if the distance between the centers of sun and earth is 1.5xx10^(8) km, calculate the force of gravitation between them.

Assuming the mass of Earth to be ten times the mass of Mars, its radius to be twice the radius of Mars and the acceleration due to gravity on the surface of Earth is 10 m//s^(2) . Then the accelration due to gravity on the surface of Mars is given by

If the earth is a point mass of 6xx10^(24) kg revolving around the sun at a distance of 1.5xx10^(8) km and in time T = 3.14 xx10^(7)s . then the angular momentum of the earth around the sun is

About 4xx10^(9)kg of matter is converted into energy in the sun each second. What is the power output of the sun ?

Mars has a diameter of approximately 0.5 of that of earth, and mass of 0.1 of that of earth. The surface gravitational field strength on mars as compared to that on earth is a factor of -
