Two metallic plate A and B
Two metallic plate A and B , each of area 5×10−4m2 , are placed parallel to each at a separation of 1cm plate B carries a positive charge of 33.7×10−12C A monocharonatic beam of light , with photoes of energy 5eV each , starts falling on plate A at t=0 so that 1016 photons fall on it per square meter per second. Assume that one photoelectron is emitted for every 106 incident photons fall on it per square meter per second. Also assume that all the emitted photoelectrons are collected by plate B and the work function of plate A remain constant at the value 2eV Determine (a) the number of photoelectrons emitted up to i=10s,
