What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6xx10^(24) kg and radius of the earth is 6.4xx10^(6)m )

What is the magnitude of the gravitational force between the earth and 1 kg object on its surface ? (Mass of the earth = 6 xx 10^(24)kg and radius of the earth = 6.4 xx 10^(6)m ) Ans. Gravitational constant,

A rocket is fired vertically with a speed of 5 km s^-1 from the earth’s surface. How far from the earth does the rocket go before returning to the earth ? Mass of the earth = 6.0 xx 10^24 kg , mean radius of the earth = 6.4 xx 10^6 m , G = 6.67 xx 10^-11 N m^2kg^-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 = 6.0xxl0^24 kg , radius of the earth = 6.4 xx 10^6 m , G = 6.67 xx 10^11 N m^2kg^2 .

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

Calculate the force of gravitation between the earth and the sun, given the mass of earth = 6xx 10^24 kg and of the sun = 2 xx10^30 kg . Average distance between the two is 1.5xx 10^10m .

Suppose you and your friend have mass 50 kg each. Suppose also that you are standing such that your centres of gravity are 1m apart. Calculate the force of gravitation between you and your friend. Calculate also the force of gravity acting on you. [Mass of the earth = 6 xx 10^(24) kg , Radius of the earth = 6.4 xx 10^(6)m ] (Use F = mg = G m M_(e)//R_(e)^(2) )

Find the mass of earth (Given the radius of earth R= 6.4 xx 10^6 m) .

Calculate the mass of the earth. Given radius of the earth =6.4xx10^-6 m and g = 9.8 m//s^2

Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth = 6 xx 10^(24) kg and the sun = 2 xx 10^(30)kg . The average distance between the two is 1.5 xx 10^(11)m .
