1. The problem statement, all variables and given/known data mass of star = 2.53 x 1030 kilograms mass of planet = 5.25 x 1024 kilograms mass of moon = 8.09 x 1022 kilograms average distance from star to planet = 1.14 x 1011 meters average distance from planet to moon = 4.59 x 108 meters Use the data above to determine the net force exerted on the moon by the planet and the star during: a. a solar eclipse. WebAssign will check your answer for the correct number of significant figures. wrong check mark N b. a lunar eclipse. WebAssign will check your answer for the correct number of significant figures. wrong check mark N 2. Relevant equations Fg=G x M1 x M2/Dsquared Note that the lineup for a solar eclipse is Sun-Moon-Earth A lunar eclipse lineup is Sun-Earth-Moon This I am sure of. 3. The attempt at a solution My attempt was to find the netforce of gravity on the moon. Here is my work which produced a wrong answer. a) Fgrav,net=Gm(moon)M(sun)/Dsquared(the distance between the star and the planet- the distance between the planet and the moon) - GM(moon)M(earth)/dsquared Perhaps I added the distances wrong- but I know when the moon is in the middle I will have opposite signs for the forces from each planet and the lunar eclipse should produce. I got 9.18E20 rounded for my answer to part a. Any ideas? Am i using the distance wrong? Any similar answers? Any other forces to be accounted for in the net sum? Thanks.
