Question

All problems must be solved in symbol form first and only then may number, be substituted and a numerical answer obtained. For full credit on all problems, your solution must contain all of The primary elements of The clear , coordinate system labeled, etc, and must be presented in a logical and orderly fashion. , with make The determination of what constitutes logical and orderly. Because I'm The grader. What is written down must, stand on its own. You are not allowed to explain your work after it has been graded. Jf explanations are needed to understand what has been done, then they should be included as part of The solution. Use scratch paper (all you need) for The solutions to The problems. Good luck!!! 1. In The figure below, there are two fixed charges +Q, and a movable charge of +q shown at point A. Consider three possible ways you could move The charge at point A: from A to B, from A to C, or from A to D. Rank these three moves in order of The most amount of work you'd have to do for that move down to The least. Make sure to take sign into account - a negative work is less than a positive work, no matter The number. Show your work to receive full credit.

Solving Question 2 only .

In an electric field E, the torque applied to a dipole P is given vectorially by the cross-product
P x E

The maximum magnitude of that torque is cross product of E vetor and P vetcor = Tmax (it occurs when P and E are perpendicular,thetha = 90):
Tmax = (6.2 * 10^-30 x 3.00 * 10^8 )
Tmax = 1.86 10^-21 N.m

part B :

Potential energy can be foind by using which is dot product of p vector and E vector

U = - p.E

U = - 1.86*10^-21 N.m
