[题目] Two large parallel plates are separated by a distance of 5 cm, The
plates have equal but opposite charges that create an electric field
in the region between the plates, An "q" particle(q=3.2*10^(-19)C,m=
6.68*10^(-27)kg)is released from the positively charged plate, and it
strikes the negatively charged plate 2*10^(-6)sec later. Assume that
the electric field between yhe plates is uniform and perpendicular to
the plates, what is the strengh of the electric field and potential
difference between the plates
[瓶颈] 电场我会算，而且算出来的跟答案一样 E = 522(N/C)
但是电压不是 V = Ed 吗 可是答案给 V = 18.3V
我有哪边没注意到吗
