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 -

The mass and diameter of a planet are half of thast of the earth. The ratio of gravitational potential energy of a body on the surface of the planet to that on the surface of the earth is

Radius of earth is 6400 km and that of mars is 3200 km. Mass of mars is 0.1 that of earth's mass. Then the acceleration due to gravity on mars is nearly

Radius of earth is 6400 km and that of mars is 3200 km. Mass of mars is 0.1 that of earth's mass. Then the acceleration due to gravity on mars is nearly

Mars is the nearest planet to the Earth.

What is the strength of earth's magnetic field at the surface of earth?

The value of G on the mars is different than earth,Is it true?

The mass of the moon is about 1.2% of the mass of the earth. Compared to the gravitational force the earth exerts on the moon, the gravitational force the moon exerts on earth

The mean diameters of Mars and Earth are 6.9 xx 10^3 km and 1.3 xx 10^4 km, respectively. The mass of Mars is 0.11 times Earth's mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b) What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?

The mass of planet mars is 1/10 th of the mass of earth and radius is 1/2 of the radius of earth. If the scape velocity at the earth is 11.2km/s, then the scape velocity at Mars will be
