2. What is the force of gravity between two 1000 kg cars separated by a distance of 20 m on a highway?Fg=r2Gm1m1Where G is the gravitational constant and r is the distance between the two objectsNow we can start plugging in the valuesG = 6.67 x 10^-11m1 = 1000 kgm2 = 1000 kgr = 20 mPlugging these into the equation yields us:Fg = 1.67 x 10^-7 N3. Using the force, calculated in # 2 above, and the weight of the car, calculate: Force (from #2) divided by the weight of car

We would apply the formula for calculating the gravitational force which is expressed as

Fg = Gm1m2/r^2

where

m1 and m2 are the mass of the bodies

G = 6.67 x 10^-11

r is the distance between them

From the information given,

m1 = 1000

m2 = 1000

r = 20

Thus,

Fg = 6.67 x 10^-11 x 1000 x 1000/20^2

Fg = 0.17 x 10^-7 N

3) Force/weight = 0.17 x 10^-7/1000 x 9.8

Force/weight = 17.02 x 10^- 12
