Question

A penny being elecelectrically neutral contains equal amount of positive and negative charge.. what is the magnitude of these charges??

Answer 1

If ur penny contains +10c charge nd -10c charge, then ur penny is electrically neutral

Answer 2

No its wrong.. ur answer is totally wrong..

Answer 3

10-10=0 coul

Answer 4

It was my typing mistake. Sorry.....

Answer 5

It is a long numerical

Answer 6

I am not getting ur answer.. what will b for copper penny..??

Answer 7

The magnitude of the charge of a electron or a proton in a penny are \[1.6X10^{-19}Coulomb \]in the CGS system. Now you need to count them in your penny to calculate the total magnatude of each elementary charge, regardless they will be equal and the net charge will be 0 as the charges are equal and opposite. Use the element chart for copper and zinc and whatever else is used to manufacturer a penny. You will need to know the mass (amount) and each element to calculate the number of atoms. You better start counting now.

Answer 8

Thankss.. here is my answer.. i solve it and got my answer..

Answer 9

That was quick, good luck with your studies. However, your answer did not appear.

today was my paper.. and i had this question in question my paper.. thankss too youu for helping me tomorrow to get the answer..

Answer 11

Good luck. It is a strange problem. I don't know how the answer can be exact. If it is a U.S. penny, the make up varies from time to time. Today's penny (I have heard) has some zinc as well as copper. Could you post what they said the answer was?

Answer 12

Here is a link that outlines the kinds of metal that makes up a penny.

Answer 13

It was a copper penny which i calculated the answer.. How can i post pic here?? I have solve it on pages.. i am new here.. so i duN Knw how to attach pik here..

Answer 14

U know every penny is made by molecules. Right??

Answer 15

Molecules made by atoms

Answer 16

Atom has equal numbers of electrons nd protons

Answer 17

U know an electron has negative charge which equal to the charge of a proton. Protons's charge is positive

Answer 18

So chargd of 1 electron is just cancelled the charge of 1 proton . Right??

Answer 19

If ur atom of given penny has 6 electrons. It must have 6 protons too. So charge of 6 electrons r equal nd oposit of the charge of 6 protons. So charges will b cancelled each other. Atom is neutral. Molecules r neutral. Penny is neutral

Answer 20

Yes yes right..

Answer 21

Thanks alooot

Answer 22

U r most welcome!!!

Answer 23

Plz feel free to ask for more clarification. I wanna help u!!!!!

Answer 24

Okay i am not good in physics.. should i ask more questions here?? Or on an another post??

Answer 25

Another post plz!!!!!

Answer 26

Okay okay..

Answer 27

Yes, the problem states that the charges do indeed cancel each other, that they are equal and opposite etc. But, the problem then asks for the magnitude of these charges. The problem states it is aware that the charges neutralize each other!

Personally I think they are asking for a ridiculous answer, and is a waste of the student's time.

Answer 28

Hmm yes it was like we calculated answer my comparing moles Numbrr,number of atoms and avagadro's number and then value of elecron..

Answer 29

Congratulations, keep up the good work.
