An indinitely  long positively charged  wire has a linear charge density `lambda cm^(-1)`. An electron is revolving  around  the wire as its center with a constant velocity in a circular plane perpendicular to the wire. Deduce  the expression for KE of electron. Plot a graph of K.E as a function of charge density `lambda`.
