Problem: An electric dipole consists of 1.0 g spheres charged to 2.0 nC at the ends of a 13-cm-long mass less rod. The dipole rotates on a frictionless pivot at its center. The dipole is held perpendicular to a uniform electric field with field strength 1000 V/m, and then released.
Part A: What is the dipole's angular velocity at the instant it is aligned with the electric field?
I need help to find the dipole's angular velocity at the instant it is aligned with the electric field.
