What do statements like these talking about infinity mean in electrostatics and electric potential?
Eg. electric potential is zero at infinity.
eg. The figure shows four pairs of charged particles. For each pair, let V = 0 at infinity and consider Vnet at points on the x axis.
+33654 The first statement means if you are far away (an infinite distance) from a charged particle (say) then the electric potential due to that particle is insignificant (zero).
For the second statement I can't see the image - it only appears as an icon in my browser.
