An area with excess electrons has a net charge; an area with a deficit of electrons has a net charge. question 10 options: negative, positive positive, negative positive, neutral negative, neutral

negative, positive

Explanation:

A we know that the electrons have a negative charge.

So, when a body has some excess electrons, it means it has negative charge.

When a body has an deficiency of eletrons, it means it gains a positive charge.

An area with excess electrons has a net _negative__ charge; an area with a deficit of electrons has a net _Positive charge.
