GO In an oscillating LC circuit, L = 25.0 mH and C = 7.80 µ F. At time t = 0 the current is 9.20 mA, the charge on the capacitor is 3.80 µ C, and the capacitor is charging. What are (a) the total energy in the circuit, (b) the maximum charge on the capacitor, and (c) the maximum current? (d) If the charge on the capacitor is given by q = Q cos( ωt + ϕ ), what is the phase angle ϕ ? (e) Suppose the data are the same, except that the capacitor is discharging at t = 0. What then is ϕ ?

The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
