What is the gravitational force between two 10 kg iron balls separated by a distance of 0.1 m?
f = G * 10 * 10 / (0.1^2)
To calculate the gravitational force between two objects, we can use Newton's law of gravitation:
F = (G * m1 * m2) / r^2
where F is the gravitational force, G is the gravitational constant (6.67430 × 10^-11 N m^2 / kg^2), m1 and m2 are the masses of the two objects, and r is the distance between the two objects.
In this case, the masses of the two iron balls are both 10 kg, and the distance between them is 0.1 m. Plugging these values into the equation:
F = (6.67430 × 10^-11 N m^2 / kg^2) * (10 kg * 10 kg) / (0.1 m)^2
F = (6.67430 × 10^-11 N m^2 / kg^2) * 100 kg^2 / 0.01 m^2
F = 6.67430 × 10^-11 N m^2 / kg^2 * 10,000 kg^2 / 0.01 m^2
This simplifies to:
F = 6.67430 × 10^-11 N * 1,000,000 N
F = 6.67430 × 10^-5 N
Therefore, the gravitational force between two 10 kg iron balls separated by a distance of 0.1 m is approximately 6.67430 × 10^-5 N.
To calculate the gravitational force between two objects, we can use Newton's law of universal gravitation. The formula is:
F = (G * m1 * m2) / r^2
Where:
F is the gravitational force
G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2/kg^2)
m1 and m2 are the masses of the two objects
r is the distance between the two objects
In this case, the two iron balls have a mass of 10 kg each and a distance of 0.1 m between them. Plugging these values into the formula, we get:
F = (6.67430 × 10^-11 N m^2/kg^2 * 10 kg * 10 kg) / (0.1 m)^2
Simplifying further, we have:
F = (6.67430 × 10^-11 N m^2/kg^2 * 100 kg^2) / 0.01 m^2
F = (6.67430 × 10^-11 N m^2) / 0.01
F ≈ 6.67430 × 10^-9 N
Therefore, the gravitational force between the two 10 kg iron balls separated by a distance of 0.1 m is approximately 6.67430 × 10^-9 N.
