# A 10 nC charge sits at a point in space where the magnitude

### Resolved Question:

A 10 nC charge sits at a point in space where the magnitude of the electric field is 1500 N/C. What will the magnitude of the field be if the 10 nC charge is replaced by a 20 nC charge?

David :

hello, welcome to JA, here is the answer:
you have charge sitting at the point where the electric field is given, so it really does not matter what is the magnitude of the charge.
The answer is the same 1500 N/C

hope this helps

David :

let me know if you have any Physics or Math question and I'll be glad to assist. Just start your post with "For David" and I'll revert immediately if I'm online.

Customer :

hello can you show how you got 1500 N/C. i wont get credit from my professor without showing any work thank you

David :

Look, the explanation is above.

David :

The external field is given to you 1500 N/m, it does not depennd what charge is placed in that field.

David :

So changing the charge from 10nC to 20nC would not alter the external electric field at the location of the charge.

David :

This was an explanation why the answer is 1500 N/C

David :

let me know if you have any questions.
