Help polishing off a Classical E&M HW question

In summary, the conversation discusses a homework problem involving showing the equality of (p dot gradient operator)E and Gradient operator(p Dot E), where p represents the dipole moment and E is a non-constant electric field. The person providing the summary suggests seeking help from two physicists, srastgoo and jsharma, who have expertise in quantum and applied physics respectively. They also suggest using vector algebra rules to expand the equation.

Homework Statement


This isn't the whole homework problem but I need to show that (p dot gradient operator)E is equal to Gradient operator(p Dot E)


Homework Equations



P= Dipole Moment
E= non constant electric field.

The Attempt at a Solution


Like I said this is the last part of the problem, I just can't make this jump.

Neumann12,

I know of two physicists who can properly explain your homework and help you understand it. One ("srastgoo") is a Ph.D. candidate in quantum physics with a specialization in black holes. The other ("jsharma") has a Master's in applied physics. For the sole purpose of helping you reach these persons, I am giving you a homework help link that will lead to both of them.

After clicking on the link, register on the site (it's free) and submit a Solution Request. The important part is to enter "srastgoo" in the Specialist's username field. You can also do the same for "jsharma" with a separate Solution Request.

Please post back to me here and let me know which one of them helped you and how well they explained your homework question.

Have you tried expanding the (p dot gradient)E with some vector algebra rules? I'm not saying it will work, but it seems like the obvious way to start to me.
 

1. What is Classical E&M?

Classical E&M (Electromagnetism) is a branch of physics that deals with the study of electromagnetic fields and their interactions with electrically charged particles.

2. What is the purpose of polishing off a Classical E&M HW question?

The purpose of polishing off a Classical E&M HW question is to ensure that the solution is accurate and meets the requirements of the question. This involves checking for any errors, simplifying complex equations, and providing a clear and concise explanation.

3. How do I approach a Classical E&M HW question?

The best approach to a Classical E&M HW question is to first understand the concepts and equations involved. Then, carefully read and analyze the question to determine the necessary steps to solve it. It is also helpful to break the problem into smaller parts and to show all work and calculations.

4. What are some common mistakes to avoid when polishing off a Classical E&M HW question?

Some common mistakes to avoid when polishing off a Classical E&M HW question include incorrect use of equations, mathematical errors, and not providing enough explanation or detail in the solution. It is important to carefully check for any mistakes and to double-check all calculations.

5. Can I use online resources to help me with a Classical E&M HW question?

Yes, you can use online resources to help you with a Classical E&M HW question. However, it is important to use reputable sources and to understand the concepts and equations yourself rather than simply copying an answer. It is also recommended to ask a teacher or tutor for assistance if needed.
