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 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) .

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)

Two identical spheres are placed in contact with each other. The force of gravitation between the spheres will be proportional to ( R = radius of each sphere)

The gravitational force between two identical objects at a separation of 1m is 0.0667 mg-wt. Find the mass of each object ( G = 6.67 xx 10^(-11) Nm^(2)//kg^(2) and g = 10m//s^(2) )
