If lithium ion Li+2 is treated as a classical system of one electron of charge ?e going around a nucleus of charge 3e on a circle of radius 1.77× 10?11 m, find the ionization energy of the electron (minimum energy needed to remove the electron).
eV.
Three charges q1=1.00 ?C, q2=?1.00 ?C, and q3=2.00 ?C are placed in the xy plane with q1 at the origin of the coordinates, q2 on the x axis at x2=3.00 m, and q3 atx3=2.00 m and y3=3.00 m. What is the total electric potential energy of the three-charge system measured from the point with all of them infinitely apart?
mJ.
