At the Moment of a Total Eclipse, the Moon Lies

question 7

Short Answer

At the moment of a total eclipse, the moon lies along a line from the Earth to the sun. If your normal weight is 600 N, how much is your weight decreased by the combined pull of the sun and moon?
M_SUN = 2.0 × 10³⁰ kg,
r_S-E = 1.5 × 10⁸ km
M_MOON = 7.4 × 10²² kg,
r_M-E = 3.8 × 10⁵ km
