Can a particle ever mov 8p),w (rqm8icx0hzu ce from a*t 6b6 ox2m x+ xlwf1+sd:auqn region of low electric potential to one of high potential and yet have itsulm++aqd1o*:x 6x n6swb tfx 2 electric potential energy decrease? Explain.
参考答案:
A negative particle will
have its electric potential energy decrease if it moves from a region of low
electric potential to one of high potential.
By Eq. 17-3, if the charge is negative and the potential difference is
positive, the change in potential energy will be negative, and so decrease.
