WebThis physics video tutorial explains the concept behind coulomb's law and how to use it calculate the electric force between two and three point charges. Th... WebFigure 1.4.4 – Torque on a Dipole. Multiplying the forces by the moment arms, and summing, we find that the magnitude of the torque on this dipole is: (1.4.2) τ = 2 [ q E d 2 sin θ] = q d E sin θ. The magnitude of the dipole moment appears in the equation, as does the strength of the electric field, and the sine of the angle between them. goliath awaits book
