What is the force of gravity between two spheres that have a mass of 8 kg and are separated by 27 m?

To calculate the force of gravity between two spheres, we can use Newton's law of universal gravitation. According to this law, the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The formula for the force of gravity (F) between two objects is:

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

Where:
- F is the force of gravity
- G is the gravitational constant (approximately 6.67430 × 10^-11 N*(m/kg)^2)
- m1 and m2 are the masses of the two objects
- r is the distance between the centers of the two objects

In this case, the masses of the spheres are both 8 kg, and the distance between their centers is 27 m. Plugging these values into the formula, we get:

F = (6.67430 × 10^-11 N*(m/kg)^2) * (8 kg * 8 kg) / (27 m)^2

Now, we can calculate the force of gravity between the two spheres.
