Need a little help with a homework problem, I don't seem to understand the theory behind this.(adsbygoogle = window.adsbygoogle || []).push({});

Figure 25-23 shows four pairs of charged particles. Let V = 0 at infinity.

Figure 25-23.

(a) For which pairs is there another point of zero net electric potential on the axis M between the particles?

ChkBox 4

ChkBox 2

ChkBox none

ChkBox 1

ChkBox 3

(b) For which pairs is there another point of zero net electric potential on the axis M to their right?

ChkBox 2

ChkBox 1

ChkBox 4

ChkBox none

ChkBox 3

If you can just give me some hints on where to start or what to look for, would appreiciate it.

Thanks for your time,
