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.

Option 4, the satellite D.

Explanation: The gravitational force between two objects is given by the formula:

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.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
