Homework Statement



At what distance from a carbon nucleus is the electric potential 2.1 V? Carbon atoms have 6 electrons in the atomic shell.


Homework Equations



v= K Q / r^2 OR K Q / r (NOT SURE)

The Attempt at a Solution



use voltage potential for point charge

Using either v= K Q / r^2 OR K Q / r (not sure)

V given, Q ( 6* electron charge) , solve for r

It's the forumula with "r" in the denominator. The "r^2" forumula is for the electric field.
