During a solar eclipse, the moon is positioned directly between earth and the sun. find the magnitude of the net gravitational force acting on the moon during the solar eclipse due to both earth and the sun. the masses of the sun, earth, and the moon are 1.99 x 10^30 kg, 5.98 x 10^24 kg, and 7.36 x 10^22 kg, respectively. the moon's mean distance from earth is 3.84 x 10^8 m, and earth's mean distance from the sun is 1.50 x 10^11 m. the gravitational constant is g = 6.67 x 10^-11 nm^2/kg^2. what is the direction of this force? toward the sun toward earth toward venus elsewhere
