A point mass m positioned at coordinates (x, y, z) is attracted towards the origin (0,0,0) with a force whose magnitude is gmr-2 where g is an acceleration-related constant and r is the distance between the point mass and the origin. Assuming that both m and g are known, derive an expression for the force field f at any point in the 3D frame apart from the origin, Show that, aside the origin, the force field is conservative and derive its potential function o, such that f= Vo.

Question
A point mass m positioned at coordinates (x, y, z) is attracted towards the origin (0, 0, 0)
with a force whose magnitude is gmr-2 where g is an acceleration-related constant and r is
the distance between the point mass and the origin.
Assuming that both m and g are known, derive an expression for the force field f at
any point in the 3D frame apart from the origin,
Show that, aside the origin, the force field is conservative and derive its potential
function o, such that f = Vo.
