Question 9 listenwhen a satellite is at a distance d from the center of the earth, the force due to gravity on the satellite is f. what would the force due to gravity on the satellite be when its distance from the center of the earth is 3d? f9f

F/9

Explanation:

There's Newton formula for attraction force between 2 objects with mass and a distance between them:

where G is the gravitational constant. are the masses of the 2 objects. and d is the distance between them.

Consider that the distance variable is squared and in the denominator of the formula. So in the case where the distance is tripled to 3d, the masses stay the same, the gravitational force would be reduced by times

So the new force would be F/9

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered
