Answer:
The force of gravity a newborn and the obstetrician is 8 x N.
The obstrcian exerts 1.87 times more gravitational force on the baby than the mars.
Explanation:
given information:
baby's mass, = 3 kg
obstericianás mass, = 100 kg
distance, d = 0.5 m
the formula of gravitational force is
where
F = gravitational force (N)
G = gravitational constant (6.67 x )
m = mass (kg)
d = distance (m)
so, gravitational force of a newborn and the obstetrician
=
= 8 x N
thus, force of gravity a newborn and the obstetrician is 8 x N
mass of mars, = 6.39 x kg
distance of mars and the earth, d = 54.6 x m
therefore, gravitational force of a newborn and the mars
=
= 4.29 x N
F(obstrician)/F(mars) = 8 x N/4.29 x N
= 1.87
hence, the obstrcian exerts 1.87 times more gravitational force on the baby than the mars.
