Now, let's tackle the problem at hand. When a rocket is fired from the Earth towards the Sun, we're essentially dealing with a scenario where gravitational forces from both celestial bodies come into play. The gravitational force between two masses can be calculated using Newton's law of universal gravitation:
F=G⋅m1⋅m2r2F=r2G⋅m1⋅m2
Where:
At a certain distance from the Earth's center, the gravitational forces from the Earth and the Sun balance out such that the net gravitational force on the rocket becomes zero.
To find this point, we set up the gravitational force equations for the Earth and the Sun:
FEarth=FSunFEarth=FSun
G⋅MEarth⋅mr2=G⋅MSun⋅m(R−r)2r2G⋅MEarth⋅m=(R−r)2G⋅MSun⋅m
Where:
We can simplify this equation and solve for rr:
MEarth(R−r)2=MSunr2(R−r)2MEarth=r2MSun
MEarth⋅r2=MSun⋅(R−r)2MEarth⋅r2=MSun⋅(R−r)2
Solving this equation will give us the distance from the Earth's center where the gravitational force on the rocket is zero. This calculation involves the masses of the Earth and the Sun, as well as the distance from the Earth to the Sun.
