Hi! I am having a tough time with this question, and would just like some clarification if thats at all possible! I feel I may just be missing a key concept, however, any help is appreciated! Thanks.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Point x is .25 m away from a point charge of +4.7*10^-8 C, point Y is .65 m away. What is the potential of point X with respect to point Y?

2. Relevant equations

Ep=(kQ1Q2)/d

Where k= 9.0*10^9

And Ep is the electric potential difference

3. The attempt at a solution

Solve Ep for each individually (Points x and y)

Point Y

Ep=(9.0*10^9)(+4.7*10^-8)/(.65)

=650.77V

Point X

Ep=(9.0*10^9)(+4.7*10^-8)/(.25)

=16581.8V

Point X-Point Y = 15930.83V
