Charges 4q and -q are located at the points -2a00 and -a00

Reference no: EM13584905

Charges 4q and -q are located at the points (-2a,0,0) and (-a,0,0), respectively. Write down the potential ?(x,y) for points in the xy plane, and then use a Taylor expansion to find an approximate expression for ? near the origin, which you can quickly show is the equilibrium point. (You can set a=1 to make things simpler)
