1.	photon of energy E ejects a photoelectron from a metel surface whose work function is ϕ0. If this electron enters into a unifrom magnetic field of induction B in a direction perpendicular to the field and describes a circular path of radius r, then the radius r, is given by, (in the usual notation)
