Question

Suppose an object has a charge of 1 C and gains 6.88 * 10^18 electrons. What will the net charge of the object be in C?

Give the answer in absolute value.

It gains a charge of 1.102 coulomb, so shouldn't the net charge be 2.102 coulombs?

Answer 1

-1.6*10^-19 * 6.88*10^18 = -11*10^-1 = -1.1
so so 2.0 - 1.1 = 0.9 C

Answer 2

That's wrong, according to my class...

Answer 3

LOL, sorry but proton is positive and electron is negative.

Answer 4

What do you think would happen to every atom in the universe if protons and electrons were both positive ?
