Essay

When a particle is a distance r from the origin,its potential energy function is given by the equation U(r)= kr,where k is a constant and r = (a)What are the SI units of k?
(b)Find a mathematical expression in terms of x,y,and z for the y component of the force on the particle.
(c)If U = 3.00 J when the particle is 2.00 m from the origin,find the numerical value of the y component of the force on this particle when it is at the point (-1.00 m,2.00 m,3.00 m).
