Assume that you havea mass of 65 kg. I you are standing on the surface of Earth, What is the force of gravitational attraction between you and the earth?

To calculate the force of gravitational attraction between you and the Earth, you can use Newton's law of universal gravitation. The formula is as follows:

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

Where:
F is the force of gravitational attraction between two objects,
G is the gravitational constant (approximately 6.67430 × 10^-11 N (m/kg)^2),
m1 and m2 are the masses of the two objects (in this case, your mass and the mass of the Earth), and
r is the distance between the two objects.

Given:
Your mass = 65 kg
Mass of the Earth = 5.972 × 10^24 kg (approximately)

The distance between you and the Earth's surface can be considered as the average radius of the Earth, which is approximately 6,371 kilometers or 6,371,000 meters.

Substituting these values into the formula, we get:
F = (6.67430 × 10^-11 N (m/kg)^2) * (65 kg) * (5.972 × 10^24 kg) / (6,371,000 m)^2

Simplifying the equation gives:
F = 63,084.2 N

Therefore, the force of gravitational attraction between you and the Earth would be approximately 63,084.2 Newtons.
