Light from a monochromatic source is incident normally on a small photo sensitive surface S having work function If power of the source is W and a is the distance between the source and S then A the number of photons striking the surface per unit time will be 1 B the maximum energy of the emitted electrons will be hc 26 2 WAS 4thca 1 C the stopping potential needed to stop the most energetic photons will be e hc D photo emission occurs only if 0 x hc 26
