Mass of the spaceship 1000 kg, mass of the sun=`2xx10^(30)`kg, mass of Mars=`6.4xx10^(23)`kg, radius of Mars 3395 km, radius of the orbit of Mars =`2.28xx10^(8)`Km, G=`6.67xx10^(-11)Nm^(2)Kg^(-2).`

A space-ship is stationed on Mars. How much energy must be expended on the spaceship to rocket it out of the solar system ? Mass of the spaceship = 1000 kg , Mass of the sun = 2 xx 10^(30) kg . Mass of the Mars = 6.4 xx 10^(23) kg , Radius of Mars = 3395 km . Radius of the orbit Mars = 2.28 xx 10^(11) m, G = 6.67 xx 10^(-11) N m^(2) kg^(-2) .

A satellite orbits the earth at a height of 400 km, above the surface. How much energy must be expended to rocket the satellite out of the earth's gravitational influence ? Mass of the satellite=200 kg, mass of the earth= 6.0xx10^(24) kg, radius of the earth= 6.4xx10(6) m, G= 6.67xx10^(-11)Nm^(2)Kg^(-2) .

Calculate the mass of sum if the mean radius of the earth's orbit is 1.5xx10^(8)km and G=6.67xx10^(-11)Nxxm^(2)//kg^(2)

A satellite orbits the earth at a height of 400km above the surface. How much energy must be expanded to rocket the satellite out of the gravitational influence of earth? Mass of the satellite is 200kg, mass of earth =6.0 xx 10^(24) kg, radius of earth =6.4 xx 10^6 m , G=6.67xx10^(-11)Nm^2 kg^(-2).

Find the magnitude of the gravitational force between the Sun and the earth. (Mass of the Sun =2xx10^(30) kg, mass of the earth =6xx10^(24)kg and the distance between the centres of the Sun and the earth =1.5xx10^(11)m , (G=6.67xx10^(-11)N.m^(2)//kg^(2))

Calculate the force between the sun and jupiter. Assume that the mass of the sun =2xx10^30 kg, the mass of the jupiter = 1.89xx10^27 kg and the radius of the jupiter 's orbit = 7.73xx10^11m . (Use G=6.67xx10^(-11) Nm^2 //kg^2 )

A spaceship is stationed on mars. How much energy must be expended on the spaceship to launch it out of this kind are known as neutron stars. Certain steller objects called pulsars belong to this categor). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun =2xx10^(30)kg ).

Calculat the binding energy of the - sum system . Mass of the earth =6xx 10 ^(24) kg , mass of the sun = 2 xx 10^(30) kg, distance between the earth and the sun = 1.5 xx 10^(11) and gravitational constant = 6.6 xx 10 ^(-11) N m^(2) kg^(2)

Find the velocity of escape from the sun, if its mass is 1.89xx10^(30) kg and its distance from the earth is 1.59xx10^(8) km. Take G =6.67xx10^(-11) Nm^(2) kg^(-2)

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