An electric dipole consists of 0.900 g spheres charged to \pm 2.30 nC at the ends of a 9.00 cm -long massless rod. The dipole rotates on a frictionless pivot at its center. The dipole is held perpendicular to a uniform electric field with field strength 1010 V/m, then released. What is the dipole's angular velocity at the instant it is aligned with the electric field? Express your answer in radians per second.
