A single conservative force = (8.0 x 10-12) N where x is in meters, acts on a particle moving along an x axis. The potential energy U associated with this force is assigned a value of 24 J at x = 0.
(a) Write an expression for U as a function of x, with U in joules and x in meters.
(b) What is the maximum positive potential energy?
(c) At what negative value of x is the potential energy equal to zero?
(d) At what positive value of x is the potential energy equal to zero?
