An electric dipole in a uniform horizontal electric field of magnitude 2.5 x 105 N/C is currently at rest and makes an angle 0 = 17° with the E field. The charges have equal magnitudes q = 3.0 µC and are separated by a fixed distance 2a = 2.0 x 10-8 m. When released, the dipole swings clockwise about an axis through its center, with no friction or other damping, until it next comes to rest. At that moment, what angle will the dipole make with the E field? 2a 10 a) 11° b) 14° c) 17° d) 21° e) 24°
