Answer 2

According to Newton's Law of Universal Gravitation, the distance between the two bells is approximately 0.65 m.

Step-by-step explanation:

In this problem, we're given the mass of two bells (150 kg each) and the gravitational force between them (4.210-6 N). We can use Newton's Law of Universal Gravitation to find the distance between them. The formula for this law is:

F = (G * m1 * m2) / r^2

Where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.

First, we need to rearrange the formula to solve for r:

r = sqrt((G * m1 * m2) / F)

Now we can substitute the given values into the formula:

r = sqrt((6.67430 × 10^-11 N m^2 / kg^2 * 150 kg * 150 kg) / 4.210-6 N)

r ≈ 0.65 m
