How much work does the electric field do in moving a proton from a point with a potential of +95 V to a point where it is -37 V? Express your answer both in joules and electron volts.

_____eV

_____J

2. Relevant equations

deltaPE = q * Vba

3. The attempt at a solution

PE = (-1.6e-19)(138)

PE = 2.2e-17 J

1.6e-19 / 12.2e-17 = .007 eV
