What is the gravitational force vetween 2 15-kg packages that are 35cm apart? What fraction is this of the weight of one package?

Is there some reason you cant compute Gravitaional force

F=GM2M1/distance^2

i used this equation to solve the problem but i keep coming up to 8.1 x 10^-9, but according to my teacher's answer, it is 8.2 x 10^-8

Recheck your work.

IF you post your work, I will check it for you.

To calculate the gravitational force between two objects, we can use Newton's law of universal gravitation, which states that the force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

The formula to calculate the gravitational force (F) between two objects with masses (m1 and m2) separated by a distance (r) is:

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

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

In this case, the masses of the two packages are both 15 kg, and they are 35 cm (or 0.35 m) apart. Let's calculate the gravitational force:

F = (G * m1 * m2) / r^2
F = (6.67430 x 10^-11 N(m^2/kg^2) * 15 kg * 15 kg) / (0.35 m)^2

Now we can solve the equation:

F = (6.67430 x 10^-11 N(m^2/kg^2) * 225 kg^2) / 0.1225 m^2
F = 9.340275 x 10^-9 N

The gravitational force between the two 15-kg packages is approximately 9.34 x 10^-9 Newtons.

To calculate the fraction of this gravitational force compared to the weight of one package, we need to know the weight of one package. Weight is the force exerted on an object due to gravity and is calculated by multiplying the mass of an object by the acceleration due to gravity (9.8 m/s^2 on Earth).

Weight (W) = m * g

Where:
W is the weight of the object
m is the mass of the object
g is the acceleration due to gravity

So, once we know the weight of one package, we can calculate the fraction of the gravitational force as:

Fraction = gravitational force / weight of one package

To calculate the weight of one package:
Weight = m * g
Weight = 15 kg * 9.8 m/s^2
Weight = 147 N

Now, let's calculate the fraction:

Fraction = (gravitational force) / (weight of one package)
Fraction = 9.34 x 10^-9 N / 147 N
Fraction ≈ 6.35 x 10^-11

Therefore, the gravitational force between the two 15-kg packages is around 9.34 x 10^-9 Newtons, and this is approximately 6.35 x 10^-11 fraction of the weight of one package.
