Question

Which satellite has the greatest gravitational force with Earth?

1. Earth and Satellite A
2. Earth and Satellite B
3. Earth and Satellite C
4. Earth and Satellite D

Satellite A has a mass (kg) of 375 and the distance from Earth (km) is 320.
Satellite B has a mass (kg) of 250 and the distance from Earth (km) is 320.
Satellite C has a mass (kg) of 50 and the distance from Earth (km) is 320.
Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.

Answer 1

Answer: Option 4, the satellite D.

Step-by-step explanation: The gravitational force between two objects is given by the formula:

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

where m1 and m2 are the masses of the objects, G is a constant, and r is the distance between both objects.

From this equation, you can see that the gravitational force between two objects increments when the masses of the objects increases, and when the distance between the object decreases.

You can see that all the options are at the same distance from the earth, 320km, then the only factor that changes is the mass of the satellite.

And, based on the previous, the satellite with more mass is the satellite that has the greatest gravitational force with the earth, and this would be the satellite D, with amas of 500kg.

Answer 2

Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.

Step-by-step explanation:

The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.

Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".
