Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.

far from the earth as depicted in the figure above. The outer edge of the space station rotates
with a speed vs. (a) How long is one rotation of the space station? (b) If the astronaut of
mass, m, gets on a scale, what does it read? (c) If the astronaut moves to a point closer
apparent
to the center of the station, R' (perhaps via an elevator as shown), does their
weight increase, decrease, or stay the same? Why?

Let's say we have a M1 and M2. Let's just say. Let's examine this hypothetical situation. The first mass would be 1.50 kg and the second mass would be 2.00 kg. These two masses would then be separated by a length or we should say a distance of this L = 2.50 m. Let's say we want to place a third mass (immaterial mass) in the middle of the two masses, such that there would be no net force. Find this specific place where this would occur, and to make it easy, find the distance from the first mass towards this third mass
