The centres of two identical spheres are `50 cm` apart. If the gravitational force between the spheres be `4.0 N`, find the mass of each sphere. Given, `G = 6.67 xx 10^(-11) Nm^(2)kg^(-2)`.

The centre of two identical spheres are 1.0 m apart . If the gravitational force between the spheres be 1.0 N , then what is the mass of each sphere ? (G = 6.67 xx 10^(-11) m^(3) kg^(-1) s^(-2)) .

The centre of two identical spheres are 1.0 m apart . If the gravitational force between the spheres be 1.0 N , then what is the mass of each sphere ? (G = 6.67 xx 10^(-11) m^(3) kg^(-1) s^(-2)) .

Calculate the gravitational force of attraction between two spherical bodies, each of mass 1kg placed at 10m apart (G = 6.67 xx 10^(-11)Nm^(2)//kg^(2)) .

The mass of the Earth is 6xx10^(24)kg . The distance between the Earth and the sun is 1.5xx10^(11)m . If the gravitational force between the two is 3.5xx10^(22)N what is the mass of the sun? G=6.7xx10^(-11) Nm^(2)//kg^(2)

A particle of mass 10 g is kept of the surface of a uniform sphere of mass 100 kg and radius 10 cm. Find the work to be done against the gravitational force between them to take the particle far away from the sphere. (Take G = 6.67 xx 10^(-11) Nm^(2)//kg^(2) ?

A particle is kept on the surface of a uniform sphere of mass 100 kg and radius 10 cm. Find the work to be done per unit mass against the gravitational force between them, to take the particle far away from the sphere (you may take h=6.67 xx 10^(-11) "Nm"^(2) "kg"^(-2) )
