Two point charges -q and +q are located at points (0,0, -a) and (0,0,a) respectively. The potential at point (0,0,Z) where Z>a is
Answer is 2qa/ 4pie e° (z2 -a2)
(Please help me how to write the value of R)
The total potential at point z is 2qa/ 4πe° (z2 -a2) Explanation:
All points are at z axis so we only draw only two axis one is x axis and the other is refrence x axis.
