Question
For part A I also tried 3.99466667e-7 and it did not work :/. Also could somebody explain the why of everything thoroughly? I need to know this for a test.
Calculate the electric potential 0.360 cm from an electron.(b) What is the magnitude of the electric potential difference between two points that are 0.360 cm and 0.730 cm from an electron? (c) How would the answers change if the electron were replaced with a proton? The sign of answer (a) would change.The sign of answer (b) would change. The sign of both answers would change. Both answers would remain the same.Explanation / Answer
a)
V = k q/r = (9e9)*(-1.6e-19)/(0.00360) = -4.00 x 10^-7 V
b)
dV = k q/r1 - k q/r2 = (9e9)*(1.6e-19)/(0.00360) - (9e9)*(1.6e-19)/(0.00730) = 2.03 x 10^-7 V
c)
the sign of answer (a) would change
