Question 1072378: Calculate the electrical torque on a water molecule, about a point at its center, when the molecule is oriented perpendicular to a 760 N./C. electric field. Consider the molecule to be a system of two charges, +e and -e, separated by a distance of 0.88E-10 m. (e = 1.6E-19 C.)
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! electrical torque = -L * Q * E * sin(theta), where L is the distance, E is the electrical field, Q is the charge
:
electrical torque = (-0.88E-10) * (1.6E-19) * 760 * sin(90) = 5.4E-27
:
Note that the two charges will rotate about the center
