gravitational field strength problem-urgent help needed 1. The problem statement, all variables and given/known data Moon has a radius of 1740km, Mass of 7.35 x10^ 22kg, grav field strength of moon= 1.62Nkg^-1, distance from Earth to Moon is 380000km G=6.67x10^-11Nm^2kg^-2 The Moon's gravitational pull on the Earth causes the ocean tides. Show that the gravitational pull of the Moon on the Earth's oceans is approximately 3 millionths of the gravitational pull of the Earth on its oceans. 2. Relevant equations g = GM / r^2 g = gs R^2 / r^2 where R= radius of planet, r = distance 3. The attempt at a solution g = gs R^2 / r^2 1.62 = gs 1740x10^3 / 380000 x 10^3 (1.62 x 380000x10^3) / 1740 x 10^3 = gs 1/3000000= 3 x10^-6 3 x10^-6 x 9.81 = gs ??? Please help!
