Hi and point charge vector question

• Jim Newt
In summary, Jim is new to the forum and has a question about the strategy for "reducing the charges" in a problem involving different charges labeled E1, E2, and E3. The problem seems to have been simplified by removing some charges that cancel out to 0, making it easier to compute.

Hi all this is my first post. This looks like a great forum and hopefully I can contribute in some way to the discussion. I have a question about JPEG I attached; hopefully you all can see it.

What is the strategy for "reducing the charges"? For instance, why is -3q reduced to -2q and -2q reduced to -q etc.? Any advice would be helpful. Thanks,

Jim

Looks to me that someone wanted to create a new problem (with different charges) without redoing the diagram. They just crossed out the old charges and wrote in the new charges. The fields from the three non-zero charges are labeled E1, E2, & E3.

I think they simplified the problem by removing some charges, which cancel out to 0. It just makes it easier to compute.

Thanks for the input. Like awvvu said, it was just a simplification of the problem that made it easier to solve.
