Solving for gravitational pull

AI Thread Summary
To determine the distance from Uranus where a space probe experiences balanced gravitational forces from both Uranus and the Sun, the gravitational force formula Fg=Gm1m2/r^2 is used. In this context, m1 represents the Sun's mass and m2 represents Uranus' mass. The distance r is the distance from Uranus to the Sun, which is essential for calculations. Additionally, the masses of both celestial bodies or their mass ratio must be known to equate the gravitational forces acting on the probe. Accurate calculations will yield the required distance in kilometers.

How far from Uranus must a space probe be along a line toward the Sun so that the Sun's gravitational pull on the probe balances Uranus's pull?


Fg=Gm1m2/r^2


Would m1 be the sun's mass and m2, Uranus' mass. then what would Fg be?

Hello jaff. Welcome to PF !

If m1 is the sun's mass and m2, Uranus' mass,

and also of r is the distance Uranus is from the sun, then Fg=Gm1m2/r^2 is the force the sun exerts on Uranus.
 
thank you,

but its asking for the distance (km)

Then one piece of information you will need is the distance that Uranus is from the sun.

Other information you will need are the masses of the sun and Uranus, or at least the ratio of their masses.

You will need to express the force that Uranus exerts on the probe.

You will need to express the force that the sun exerts on the probe.

You will need to equate those two forces.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
