## Homework Statement

The first question that was asked was; What is the total charge of the radon nucleus? (The neutral radon atom has 86 electrons.)

the answer to that is 1.38*10^(-17) C

the second question asked is;

What is the magnitude of its electric field at a distance of 6.0 x10-(10) m from the nucleus?

## Homework Equations

E=kq/r^2

## The Attempt at a Solution

I tried using the equation E=kq/r^2

E=(8.99*10^9)*(1.38*10^(-17)/((6.0*10^(-10)^2))=2.07*10^(12) N/C

but this answer isn't right? I'm not sure why its not right as this is the only method I know how to do in order to solve this problem.

If someone could please show me what it is I'm doing wrong I'd really appreciate it :)
