Question 2

A potential energy function for system 1 is given by U1(x) = Cx2 + Bx3. The potential energy function for system 2 is given by U2(x) = A + Cx2 + Bx3, where A is a positive quantity.

  B) The force is identical on the two systems.
  C) The force on the second system will be with less than the force on the first system.
  D) There is no relationship between the forces on the two systems.
  E) The force on the second system will be with greater than the force on the first system.
