What is the electric potential at a point in space if a charge of 7.3 × 10-17 coulombs at that point has a potential energy of 6.4 × 10-17 joules?


0.64 volts


0.73 volts


0.88 volts


0.91 volts

Verified Answer :

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) = \(6.4 * 10^{-17} joules\)
q (charge) = \(7.3 * 10^{-17} coulombs\)

Formula:
\(V = \frac{Ep}{q}\)

Solving:
\(V = \frac{Ep}{q}\)
\(V = \frac{6.4 * 10^{-17}\:J}{7.3 * 10^{-17}\:C}\)
\(V = 0.8767...\to \boxed{\boxed{V \approx 0.88\:J/C\:or\:Volts}}\end{array}}\qquad\quad\checkmark\)
