题目 :在两个点电荷产生的电场中 ,在距点电荷有限距离处 ,我们发现有场强为零的点 ,也有电势为零的点 (选取无穷远处电势为零 ) ,则在此电场中Ａ .场强为零的点和电势为零的点有无数多个 .Ｂ .场强为零的点只有一个 ,电势为零的点有无数多个 .Ｃ .场强为零的点和电势为零的点 Title: In the electric field generated by two point charges, at a finite distance from the point charge, we find that there is a point where the field strength is zero, and there is also a point where the potential is zero (the potential is chosen to be zero at infinity), then in this field Medium A. The point where the field strength is zero and the point where the potential is zero are numerous. B. There is only one point where the field strength is zero, and there are countless points where the potential is zero. C. The point where the field strength is zero and The point at which the potential is zero
