Calculating Electrostatic Energy from Capacitance Matrix
Let's say I have two spherical conductors and I put some charge on each. As I understand it, the electrostatic energy $W$ in the fields will be equal to
$$W = \frac{1}{2}C_{11}V_1^2 + \frac{1}{2}C_{22}...

Electric Potential from separating charges [closed]
Say there are 2 charges, one of charge C, and the other with a charge of -2C. C=1.5*10^-6 C. Initially, they are right next to each other. I pull them apart to a distance of 15 cm.
So I can use the ...

Total potential energy for two charged particles
I'm trying to formulate a Lagrangian equation for a system of two charged particles. They have respective masses $m_1$ and $m_2$, and respective position vectors $\vec{x_1}(t)$ and $\vec{x_2}(t)$.

Infinite chain of alternating charge
The problem
There is an infinite chain (1d) of alternating charges that are in a distance a from each other. That is there is one charge +q and next to it -q and so on. Now calculate how much work it ...
