PARA QUES The circuit shown is placed in vacuum Both the capacitor are identical and they have the same capacitance C Light is incident on the left plate of the upper capacitor When all the switches are open then the hf versus KEmax when the electron reaches the opposite plate f is frequency of light incident is given by graph 1 When only S3 and S4 are closed then the graph becomes 2 When only the switches S1 and S2 are closed the graph becomes 3 E Q1 What is the work function of the cathode Q2 What is the value of E S E hf KE max 3 1 2
