At which point between earth and sun, the intensity of the gravity field of the earth and sun are equal, if the mass of Earth is 6 x 10 to power 24 kg, the mass of the sun is 2 x 10 to power 30 kg while the distance between them is 15 x 10 to power 7 km?
Mearth/r^2 = Msun / (15*10^7 - r)^2
r is Km from earth center
