(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An ion accelerated through a potential difference of 10V experiences an increase in kinetic energy of 7 J. Calculate the charge on the ion.

2. Relevant equations

U=qV

-qV=W

3. The attempt at a solution

My book says the charge is positive, but I think that the charge is suppose to be negative. Did the book make a mistake or am I missing something? Whether the charge is positive or negative does matter right?

Thanks for any help.
