Solve the problem.Consider a small region inside an elastic material such as gelatin. As the material "jiggles", this small region oscillates about its equilibrium position (xo, yo, zo). The force that tends to restore the small region to its equilibrium position can be approximated as F = - k(x - xo)i - k(y - yo)j - k(z - zo)k Find a potential function f for this force field.
