Answer:
10 m
Explanation:
By the Newton's Law of gravitation
F = Gm₁m₂/r²
where F = gravitational attractive force,
G = Universal gravitational constant
m₁ & m₂ = masses involved
r = distance between centers of gravity of two cars
So you get,
F = 3.0349 X 10⁻⁷ = 6.674×10⁻¹¹ ×700×650/r²
r = 10 m
So if the two cars are identical the distance between two cars is 10 m,
else the distance between the centers of gravity of two cars is 10 m
