Moving a point charge of 3.2 x 10 -19 coulomb between two points in an electric field requires 4.8 x 10 -18 joule of energy.  What is the potential difference between these points?

V = ?

W = 4.8 x 10^-18 J

q = 3.2 x 10^-19

V = W/q

    = 4.8x10^-18 / 3.2 x 10^-19

    = 15 V

Work (Joules) = 4.8 x 10^-18 ; Charge or q (Coulomb) = 3.2 x 10^-19 ; Potential difference (Volts) = ?

V = W/q

    = 4.8 x 10^-18 / 3.2 x 10^-19

    = 15 V
