Question

(870) "roblem 4: A mysterious force discovered in nature that acts on all particles in the three-dimensional space. You determine that the force is always points a definite point in space, which we can call the force center. The magnitude of the force turns out to be proportional to the distance from the force center to any other point. Your friend says that it has been determined that the constant of promotionally has been determined to be 6 (in units to be determined), Le the magnitude of the force on a particle can be written as 6/4, when the particle is at a distance from the force center 904 33% Part (a) Write an expression for the potential energy Up of a particle when it is at a distance D from the force center, where B is the constant of proportionality.
