Consider an lc circuit in which l = 490 mh and c = 0.116 �f.

(a) what is the resonance frequency ? 0?
krad/s

(b) if a resistance of 1.02 k? is introduced into this circuit, what is the frequency of the damped oscillations?

(c) by what percentage does the frequency of the damped oscillations differ from the resonance frequency?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
