An electric dipole consists of 1.30g spheres charged to ± 1.70 nC at the ends of a 15.0cm -long mass less rod. The dipole rotates on a frictionless pivot at its center. The dipole is held perpendicular to a uniform electric field by field strength 960V/m , then released.
What is the dipole's angular velocity at the instant it is aligned with the electric field?
