Aslender, uniform metal rod of mass m and length lis pivoted without friction about an axis through its midpoint andperpendicular to the rod. a horizontal spring, assumed massless andwith force constant k, is attached to the lower end of the rod, with the other end of thespring attached to a rigid support.
find the torque tau due to the spring. assume that theta is small enough that the spring remains effectivelyhorizontal and you can approximate \sin{(\theta)}\approx \theta (and \cos(\theta)\approx 1 ).
express the torque as a function oftheta and other parameters of the problem.
what is the angular frequency omega of oscillations of the rod?
express the angular frequency interms of parameters given in the introduction.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
