Two coaxial cylindrical conductors are shown in perspective and cross-section above. the inner cylinder has radius a = 2 cm, length l = 10 m and carries a total charge of qinner = + 8 nc (1 nc = 10-9 c). the outer cylinder has an inner radius b = 6 cm, outer radius c = 7 cm, length l = 10 m and carries a total charge of qouter = - 16 nc (1 nc = 10-9 c). what is ex, the x-component of the electric field at point p which is located at the midpoint of the length of the cylinders at a distance r = 4 cm from the origin and makes an angle of 30 degrees with the x-axis?
ex =?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
