Question

Dos masas con valores de 8kg y 12kg cada una se encuentran separadas por una distancia de 1m. Determinar la fuerza de atraccion gravitacional entre ellas si se compara con el valor de sus pesos Como es este valor?

Answer 1

The question is: Two masses with values ​​of 8kg and 12kg each are separated by a distance of 1m. Determine the force of gravitational attraction between them if compared with the value of their weights. What is this value?

Answer: The force of gravitational attraction between them if compared with the value of their weights is
`640.704 * 10^(-11) N`.

Step-by-step explanation:

Given:
`m_(1)` = 8 kg,
`m_(2)` = 12 kg

Distance = 1 m

Formula used is as follows.

`F = (G * m_(1) * m_(2))/(r^(2))`

where,

F = force of gravitational attraction

G = gravitational constant =
`6.674 * 10^(-11) N m^(2)/kg^(2)`

`m_(1)` = mass of object 1

`m_(2)` = mass of object 2

r = distance between the centers of these two objects

Substitute the values into above formula as follows.

`F = (G * m_(1) * m_(2))/(r^(2))\\= (6.674 * 10^(-11) Nm^(2)/kg^(2) * 8 kg * 12 kg)/((1 m)^(2))\\= 640.704 * 10^(-11) N`

Thus, we can conclude that the force of gravitational attraction between them if compared with the value of their weights is
`640.704 * 10^(-11) N`.
