Note: The unit adopted in SI for electric potential is volt (V), in homage to the Italian physicist Alessandro Volta, and the unit designates Joule by coulomb (J / C).
Data:
V (volts or J/C) = ?
Ep (potential energy) = [tex]6.4 * 10^{-17} joules[/tex]
q (charge) = [tex]7.3 * 10^{-17} coulombs[/tex]
Formula:
[tex]V = \frac{Ep}{q} [/tex]
Solving:
[tex]V = \frac{Ep}{q}[/tex]
[tex]V = \frac{6.4 * 10^{-17}\:J}{7.3 * 10^{-17}\:C}[/tex]
[tex]V = 0.8767...\to \boxed{\boxed{V \approx 0.88\:J/C\:or\:Volts}}\end{array}}\qquad\quad\checkmark[/tex]
