1. The problem statement, all variables and given/known data Given two photocells, using light sources with identical frequency and intensity, but with different metal anodes with different work functions. Which of the followings are correct: A. The stopping voltage will be identical in both cells B. The current will be identical in both cells C. The stopping voltage will be higher in the cell with lower work function D. The metal with the larger work function would result in larger kinetic energy of the photoelectrons. 2. Relevant equations E(e) = hf - W = 0.5mv^2 I = q/t 3. The attempt at a solution The answers given in the book are B and C However B seems dubious as: E(e) = hf - W , since the photocells have different work functions, the kinetic energy of electrons from the two cells should be different, and so, electrons should have different speed and so, results in different current. However B claims the current to be the same. So I need help in verifying this question (as my textbook has been proven to be untrustable many times before).
