An electron on the axis of an electric dipole is 26 nm from the center of the dipole. what is the magnitude of the electrostatic force on the electron if the dipole moment is 4.1 ✕ 10−29 c · m? assume that 26 nm is much larger than the dipole charge separation.

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.
