So Let’s Start.
The purpose of starting PhysicsCookBook is to help my students with the understanding of physics. Due to some personal reasons, after some initial days, I left it untouched. Now things settled and I am planning to start it again. I am not the video kind of guy. I don’t like my learning from videos. On…

An electric dipole is formed by two charges +q and –q located in xy-plane at (0, 2) mm
Question: An electric dipole is formed by two charges $+q$ and $–q$ located in $xy-plane$ at $(0, 2)$ mm and $(0, –2)$ mm, respectively, as shown in the figure. The electric potential at point $P(100, 100)$ mm due to the dipole is $V_0$. The charges $+q$ and $–q$ are then moved to the points $(–1,…
