Exercise on Gravitational Forces

Ftot = GMm/R2,    Ftidal = Ftot*(dR/R),      dR = Rl - Ru
G=6.67x10-11Nm2/kg2, closest approach for planets = |planet-earth|
Some Solar system statistics and effects on a m = 100kg man. Assume Rl-Ru=1m.

man 100kg 1( standing next to someone)  6.67e-7  6.67e-7
Calculate the total force and the tidal force on our 100 kg man, who is standing on the surface of the earth, due to
1) the earth
2) the sun
3) the moon
4) jupiter
5) another 100 kg man standing 1m away.

Based on your results how signifcant, physically, is the position of the planets on our 100kg man ?
 
As an example, the mass of a typical mosquito is 2.5e-6 kg. The weight of a mosquito on earth is 2.45e-5 N.
