Gravitational attraction depends on the mass of the objects as well as their distance. The gravitational force between objects i

shepuryov [24]

<h2>Answer: Gravitational attraction will be the same</h2>

According to the law of universal gravitation, which is a classical physical law that describes the gravitational interaction between different bodies with mass:

$F=G\frac{m_{1}m_{2}}{r^2}$ (1)

Where:

$F$ is the module of the force exerted between both bodies

$G$ is the universal gravitation constant.

$m_{1}$ and $m_{2}$ are the masses of both bodies.

$r$ is the distance between both bodies

Now, if we double both masses and the distance also doubles, this means:

$m_{1}$ and $m_{2}$ will be now $2m_{1}$ and $2m_{2}$

$r$ will be now $2r$

Let's rewrite the equation (1) with this new values:

$F=G\frac{(2m_{1})(2m_{2})}{(2r)^2}$ (2)

Solving and simplifying:

$F=4G\frac{m_{1}2m_{2}}{4r^2}$

$F=G\frac{m_{1}m_{2}}{r^2}$ (3)

As we can see, equation (3) is the same as equation (1).

So, if the masses both double and the distance also doubles the Gravitational attraction between both masses will remain the same.

A train travels 55 km south along a straight track in 34 minutes. What is the train's average velocity in kilometers per hour?

AURORKA [14]

Hopefully I’m not late and I apologize if I am, but the answer to your question would be 95.6 km/hr. You know you can look up your question as well to see if they already have a answer to that so you won’t waste your points.
