A particle is constrained to move along the positive x-axis under the influence of a force whose potential energy is U(x) = U_0(2 cos x/a - x/a) where U_0 and a are positive constants. Plot U versus x. A simple hand sketch is fine. Find the equilibrium point(s). For each equilibrium point, determine whether the equilibrium is stable or unstable.

Suppose a particle is constrained to move along the x-axis. There are two rings of contin- uous charge distributions (total charge each of Q) centered on the x-axis and on a plane perpendicular to it. One ring is located at x L and the other at x =-L. (a) Obtain an expression for the potential due to the ring charges as a function of z for all x-values in between a E(-L, L). Hint: you should be integrating something. b)...

A particle is constrained to move in the x - y plane. Its position as a function of time is given by x(t) = x_0 sin(w_xt) and y(t) = y_0 cos(w_yt). Find the force vector F on the particle. Under which condition is the force a central force (i.e., points in the vector r direction)? Find the potential energy for the general force that you found in part (a) (i.e., not necessarily central). Show that the particle's energy is conserved.

A bead of mass M is able to move without friction along a stationary horizontal rod (directed along the x axis). In addition, a second body of mass m is attached to the first bead and suspended below it via a massless rod of length a. This second mass and rod form a pendulum that is able to swing in the xy-plane (where y is the vertical axis). (a) Obtain the Lagrangian for the system of two masses. (b) Assuming...
