1. The problem statement, all variables and given/known data An electric dipole consists of 2.0 g spheres charged to 5.0 nC (positive and negative) at the ends of a 12 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 1400V, then released. What is the dipole’s angular velocity at the instant it is aligned with the electric field? 2. Relevant equations F=mω^2r F=qE 3. The attempt at a solution F=qE F=(5*10^-9)(1400) F=7*10^-6N 7*10^-6=mω^2r ω=√(7*10^-6/(.004*.12)) ω=.121rev/s? I'm just unsure if I did this correctly, I thought it seemed to easy that way.
