#5.5"V"#

The relationship between the change in electric potential and the voltage and charge between two points is:

#W=qV#, where:

#W# is the change in potential energy, or the work done.

#q# is the charge passing through the points

#V# is the difference in voltage.

Rearranging the equation to solve for #V#, we get:

#V=W/q#.

Here, #W=25"J"-14"J"=11"J"#, and #q=2"C"#.

Inputting these values, we get:

#V=11/2#

#V=5.5# volts.
