I don't really know the answer but maybe north pole and south pole?
Explanation:
Below is an attachment containing the solution.
Answer:

Explanation:
The change in potential energy can be expressed as:

where K is a constant with a value of
, q1 and q2 are the charges of the proton and the electron and r is the distance between them.
The charge for the proton is
and the charge for the electron is
.
Converting r=1.0nm to m:

Replacing values:


Answer:
8m/s
Explanation:
Average Speed = distance / time = 400/50 = 8m/s
