The only known force that a planet could exerts on us is gravitational, so if there is anything to astrology we should expect this force to be significant tatus for 33% Part (a) Calculate the gravitational force, in newtons, exerted on a 3.9 kg baby by a 105 kg father who is a distance of 0.16 m away at the time of its birth. ew Grade Summary 0% 100% tatus ompleted ompleted sin0 tan Submissions cos cotanOasinO acos0 atan0 acotan sinh0 cosh0tanh) cotanhO Attempts remaining: 5 (3% per attempt) detailed view ompleted ompleted ompleted ompleted 0 END Degrees Radians VO Hint I give up! | Hints: 1% deduction per hint.

m =mass of baby = 3.9 kg
M = mass of father = 105 kg
r = distance = 0.16 m
gravitational force is given as
F = G m M /r2
F = (6.67 x 10-11) (3.9) (105)/(0.16)2
F = 1.067 x 10-6 N
b)
M' = mass of jupitor = 1.9 x 1027 kg
r = distance between baby and jupitor = 6.29 x 1011m
gravitational force is given as
F' = G m M' /r2
F' = (6.67 x 10-11) (3.9) (1.9 x 1027)/(6.29 x 1011)2
F' = 1.24 x 10-6 N
c)
Calculate the ratio of forces .
F'/F = (1.24 x 10-6 )/(1.067 x 10-6 )= 1.16
