Problem

A uniform electric field of magnitude

250\,\mathrm{V\,m^{-1}}

is directed in the positive

x

-direction. A

+12\,\mu\mathrm{C}

charge moves from the origin to the point

(x,y)=(20.0\,\mathrm{cm},5.0\,\mathrm{cm})

. (1) What is the change in the potential energy of this charge? (2) Through what potential difference did the charge move?
