This sequel of the previous problem will remind you of how you find small oscillations of a classical system near its equilibrium point (they are will teach you how to treat them quantum mechanically to estimate the first few energy eigenvalues of the system, and will train you in making order of magnitude estimates a) assume that the pendulum of the previous problem performs small oscillations around its stable equilibrium point θ-0. approximate the potential energy around this point with a harmonic oscillator potential and find the classical frequency of such small oscillations. b) write the quantum hamiltonian of the pendulum for such small oscillations and find the energy spectrum of these small oscillations. (the energy levels must be expressed in terms of the constants 1, u and ћ.) c) the oscillating molecule is in its first excited state and decays into its ground state by emitting one photon. using the approximation of the previous part, determine the wave- length of the photon.

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
