Question: An electric dipole consists of 0.800g spheres charged to ± 2.40nC at the ends of a 13.0cm -long mass less rod. The dipole rotates on a frictionless pivot at its center. The dipole is held perpendicular to a uniform electric field with field strength 980V/m, then released.
Part A: What is the dipole's angular velocity at the instant it is aligned with the electric field?
I need proficient help in the above question.
