Calculate mass of earth taking it to ne a sphere of radius 6400 km. given `g=9.8 m//s^(2)` and `G=6.67xx10^(-11)N m^(2)kg^(-2)`

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

If two spheres of equal masses with centres 0.2 m part attract each other with a force of 1xx10^(-6) kg wt . What would be the value of their masses? g=9.8ms^(-2)" and "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)

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)

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

Calculate the height above the earth at which the geostationary satellite is orbiting the earth. Radius of earth = 6400km. Mass of earth = 6 xx 10^(24) kg. G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

calculate the gravitaional intensity and graviational potential at a location which is from the surface of the Earth at a height 4 times the radius of the surface. R_(e) = 6400 km , G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) , M_(e) = 6 xx 10^(24) kg .
