Looks like you have the right equation and all the needed information. Check to make sure you are entering everything into your calculator properly. Simply solve the equation for R.

The formula is right, the answer is way, way off. How did you get it?

The G in the universal law of gravitation is not the same as g=9.81m/sec which is the acceleration due to gravity at the Earth's surface. It's 6.67*10^(-11)*m^3/(kg*sec^2). Try keeping track of units.

Oh, well then what is the G? because i have no clue.

I just edited to quote it. But you could look it up.

24.713 is the answer right?

If you say 24.713m, I'll agree with that. Put units on things. If you'd done that you would have realized 9.8m/sec^2 couldn't be the G you want. Because you wouldn't have gotten an answer in meters.

physicsbhelp, please don't delete all your posts after you have received help. It makes the thread totally unreadable, and useless to anyone else!
 

1. What is Universal Gravitation Problem?

The Universal Gravitation Problem is a scientific concept that explains the force of gravity between two objects in the universe. It was first described by Sir Isaac Newton in his law of universal gravitation.

2. How does gravity work?

Gravity is a fundamental force of nature that causes all objects with mass to be attracted to each other. The magnitude of this force is directly proportional to the masses of the objects and inversely proportional to the square of the distance between them.

3. What is the formula for calculating the force of gravity?

The formula for calculating the force of gravity is F = G * (m1 * m2)/d^2, where F is the force of gravity, G is the universal gravitational constant, m1 and m2 are the masses of the objects, and d is the distance between them.

4. How does the Universal Gravitation Problem relate to other scientific theories?

The Universal Gravitation Problem is a fundamental aspect of physics and is closely related to other scientific theories such as Newton's laws of motion, Einstein's theory of general relativity, and the Standard Model of particle physics.

5. What are some real-world applications of the Universal Gravitation Problem?

The Universal Gravitation Problem has numerous real-world applications, including predicting the motion of celestial bodies, understanding the orbits of planets, and designing spacecraft trajectories. It also plays a crucial role in fields such as astronomy, astrophysics, and cosmology.
