Equipotential lines for two charges

AI Thread Summary
As two like charges move closer together, their equipotential lines begin to resemble those of a single charge, reflecting the combined magnitude of both charges. In this limiting case, the effective charge becomes twice that of the original. The density of the equipotential lines increases as the charges approach, indicating a stronger electric field in that region. This phenomenon illustrates how the spatial arrangement of charges affects the distribution of electric potential. Understanding this behavior is crucial for analyzing electric fields in various configurations.

Hi there,

Could you describe for me what happens to the equipotential lines of two charges as they move close to each other.

Thanks

In the limiting case the two charges will be at one point, resembling the field of a single charge (with the magnitude of both charges combined.) So, when you move two like charges closer to each other, the equipotential lines will start to look more and more like that of a single charge.
 
Thanks, exactly when I have been looking for.
 
The charge's magnitude is twice that of original, though, which means that the equipotential lines will be packed more dense than with two single charges separated by great distance.
 
Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
