Physics [Help, need answer in 10 min]

During a solar eclipse, the moon (of
mass 7.36 × 1022 kg), Earth (of mass
5.98 × 1024 kg), and Sun (of mass
1.99 × 1030 kg) lie on the same line, with the
moon between Earth and the Sun.
What gravitational force is exerted on the moon by the Sun? The universal gravitational constant is 6.673 × 10−11 N · m2/kg2, the Earth-moon distance is 3.84 × 108 m, and the Earth-Sun distance is 1.496 × 1011 m. Answer in units of N.

  1. Never come here expecting instant help. Someone who can do it may not be available just now. Still, this problem seems pretty straightforward:

    F = GMm/r^2 =

    6.673*10^-11 * 1.99*10^30 * 7.36*10^22
    -------------------------------------------
    (1.496*10^11 + 3.84*10^8)^2

    = 4.345*10^20 N

    The earth's mass does not matter.
