In a photocell bichromatic light of wavelengths 2475˚A and 6000˚A are incident on cathode whose work function is 4. 8eV. If a uniform magnetic field of 3×10⁻⁵ Tesla exists parallel to the plate, the radius of the path describe by the photoelectron will be (mass of electron =9×10⁻³¹kg )
A) 1cm
B) 5cm
C) 10cm
D) 25cm
