What is the charge on an object that has 1.09x10^13 excess electrons?

Explanation:

The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :

which is known as fundamental charge.

For an object containing N excess electrons, the total charge of the object is

In this problem, the number of excess electrons in the object is:

Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:

lexy is right because she has the labeled s

object 2 because all the other ones are wrong
