Answer #1

F_{EM}=1.99*10^{20}N

F_{SM}=4.61*10^{20}N

As F_{EM}\ and\ F_{SM} are in perpendicular direction, we can denote these two forces along x- and y-directions respectively.

So, the net force on the moon is given by,

F_{net}=\sqrt{(F_{EM})^2 + (F_{SM})^2}

So, F_{net}=\sqrt{(1.99*10^{20})^2 + (4.61*10^{20})^2}=5.021*10^{20}N (Answer)

  • What us the acceleration?

    When the Moon is directly overhead at sunset, the force by Earth on the Moon, FEM, is essentially at 90° to the force by the Sun on the Moon, FSM, as shown below. Given that FEM = 1.98 ✕ 1020 Nand FSM = 4.36 ✕ 1020 N, all other forces on the Moon are negligible, and the mass of the Moon is 7.35 ✕ 1022 kg, determine the magnitude of the Moon's acceleration (in m/s2)
