Print -11-3-4 -121-5 -n 1M -R 0/1.3 1/23 (4.3%) Assignment Scoring 16 6.5 P039 Astrolo gy, that unlikel y known force a planet ex agnitude of the gravitational force (in N) exerted on a 5.00 kg baby by a 130 kg father 0.150 m away at birth (he is assisting, so he is close to the child.) (b) Calculate the magnitude of the force on the baby (in N) due to Jupiter if it is at its closest distance to Earth, some 6.29 x 10i m exert similar gravitational forces. (Of course, there could be an unknown force it.) acting, but scientists first need to be convinced that there is e ven an effect, much less that an unknown force causes Missing Plug-l How does the force of Jupiter on the baby compare to the force of the father on the baby? 6

Explanation / Answer

a) gravitational force is Fg = G*m1*m2/d^2

G is the universal gravitational constant = 6.67*10^-11 N-m^2/kg^2

m1 = 5 kg

m2 = 130 kg

d = 0.15 m

then Fg = G*m1*m2/d^2 = (6.67*10^-11*5*130)/0.15^2 = 1.93*10^-6 N

b) Fjupiter = G*m1*m2/d^2

m1 is the mass of the jupiter = 1.9*10^27 Kg

m2 = 5 kg

d = 6.29*10^11

Fjupiter = (6.67*10^-11*1.9*10^27*5)/(6.29*10^11)^2 = 1.6*10^-6 N

Ffather /Fjupiter = (1.93*10^-6)/(1.6*10^-6) = 1.21
