Answer the following statement(s) true (T) or false (F)
1. Consider a uniformly charged circular loop and a uniformly charged straight wire. These two charge distributions create very different electric fields in the empty space that surrounds them. Even so, the divergence a distance r from the center of the loop along its axis and the divergence the same distance r from the wire’s center have the same numerical value.
