Q 11 SUBJECTIVE NUMERICAL Three monochromatic sources having wavelengths 12 42 nm 6 21 nm and 24 84 nm are placed close to each other in front of a converging lens such that equal powers from the three equal to 1 mW each fall on a converging lens and then on a small spherical conductor of radius r 1 cm and work function 62 1 eV Assume 50 efficiency of emission and no change in effective value of work function due to photoelectric emission and potential rise Use hc 1242 eV nm all electrons emitted by the sphere are immediately removed by some non electrical mechanism At t 8 s switch S is closed so that the sphere gets connected to the earth via resistor of value 6 75 MQ Find the current in A flowing just after the switch is closed af 12 42 nm 6 21 nm 24 84 m a pequffu atat c yg ffu u mg Chat Act 34 Uhr zu Ga 1 mWz a vu da uz ufa r 1 cm 62 1 eV yg ott nu ma a 50 faya fa am faua df ku hd da urada as stai hc 1242 M Gu 3Afa A V nm fe ufaydu Mu faw ge si suu S3 cl a 2 G 6 75 M qe au a 31 J141 Rda ch are the di gara sta A A S D S ufaduh ha ch R www Ground RT
