can you have a - electric field due to a negative source charge. every book uses a + source energy and gets a + electric field. I am using he formula E=kQ/r^2.


Thanks

Yes.

yes you can, and you can use the equation you're using to get it. You'll get a negative electric field which means that it's "flowing" into the negative charge. I'm not sure how familiar you are with electric fields but an electric field flows into a negative charge.

Both posts have it right. Electric field is a vector quantity, the only difference b/t fields created by + VS - charges is its direction. If one points North, the other points South and as Cjc555777 they point from + to - charges.
