1. ## Field strength2

In a hydrogen atom, the electron and the proton are seperated by an average distance of 5.3x10^-11m. What is the field strength from the proton at the position of the electron?

$|E|=\frac{-e}{4\pi \varepsilon_0 (5.3 \times 10^{-11})^2}$

where e is the charge on an electron, or -e the charge on a proton.

3. The answer in the text says 3.6x10^4N/C toward smaller charge but I got 1.08x10^5N/C if I used the(1m)^2 in my calculations

This comment belongs in the other thread. There you are adding when you should be subtracting as the two field components act in opposite directions.
