$5.5"V"$

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.
