Step 1
The change in potential energy is given by the equation: ΔPE = qΔV where ΔPE is the change in potential energy, q is the charge, and ΔV is the change in potential. In this case, the charge of the proton is q = 1.6 x 10^-19 C, and the change in potential is ΔV = Show more…

(I) How much work does the electric field do in moving a proton from a point with a potential of $+125 \mathrm{V}$ to a point where it is $-55 \mathrm{V}$ ? Express your answer both in joules and electron volts.
A point charge $q_{1}=+2.40 \mu C$ is held stationary at the origin. A second point charge $q_{2}=-4.30 \mu C$ moves from the point $x=0.150 \mathrm{m}, y=0,$ to the point $x=0.250 \mathrm{m},$ $y=0.250 \mathrm{m} .$ How much work is done by the electric forceon $q_{2} ?$
