dl.US.CUU Quiz: Quiz 13 RL circuits with DC z: Quiz 7 Circuits Question 2 Quiz: Quiz 8 Dipole mom 1 pts In PHY 231 you learned that the work in rotational motion can be written as W = d. Using the torque from the previous question, determine the work done by the field on the dipole moment while aligning it with the filed lines. Start from a lower limit of 90 degrees in the integral and end with a 0 degrees as upper limit. Turning the dipole from a configuration where it is perpendicular to the field to a configuration where it is parallel to the field. You will need to include a "minus" sign at the beginning of your integral since the angle theta goes from high to low. Try to take the integral of the torque and find the potential energy associate with it. Do not forget that W -AU U at 90 is zero and U= -. The configuration is stable when the dipole moment is oriented parallel the field lines, no more twisting of the molecule. U at 90 is zero and The configuration is unstable when the dipole moment is oriented parallel the field lines when the angle theta is zero. (Theta in my picture on Question 1) U at 90 is zero and U = -2p. The configuration is stable when the dipole moment is oriented parallel the field lines, no more twisting of the molecule. The energy cannot be the dot product of two vectors because it is a scalar.

Answer 1

DATE= Torque about point A =) TaqEx d sino => I = Pesino .: work dones we stao = w: Spesino de : -PECOSO +C -) w = - PECOSB + C {:w=0) At oc P.E. = W=0. .. Potential energy (U) = - PECOSO = US - PE • option CAS is OP TIO correct.
