An isolated conducting sphere of radius 10cm, initially uncharged, is illuminated by ultraviolet light of wavelength 210nm. With each photoelectron emitted from the conductor, there will be an increasing positive charge building on the surface of the sphere. A) What is the maximum kinetic energy of the first electron emitted from the surface of the sphere? B) What is total charge(maximum) that the photoelectric effect will induce on the sphere? The work function for this conductor is 1.6eV. State the answer in pc to the nearest hundredth of pC. Take Planck's constant to be h = 6.626*10-34 J-s, the speed of light to be c = 3*108 m/s, 1eV = 1.6*10-19 J, and the mass of an electron to be me = 9.11*10-31 kg=0.511MeV/c2 Take the permittivity of free space to be 0 ke 8.99x109 Nm/c2 NOTE: 1pC=1 picoCoulomb =1x10-12 C. 1e=1.6x10-19 C. 1 4ke
