Can a particle ever moa:h76i qm v7p8x9q hc1 j,khrove from a region of low electric pote*8/rhe * zecant:m0jfntial to one of high potential and yet have its elec mh:z8 0trae*ef*c/n jtric 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.
