A) \[9.61\times {{10}^{14}}per\ \sec \]per sec
B) \[4.12\times {{10}^{13}}per\ \sec \] per sec
C) \[1.51\times {{10}^{12}}per\ \sec \] per sec
D) \[2.13\times {{10}^{11}}per\ \sec \] per sec
Correct Answer: C
Solution :
Intensity of light \[I=\frac{Watt}{Area}=\frac{nhc}{A\lambda }\] Þ Number of photon \[n=\frac{IA\lambda }{hc}\] \ Number of photo electron = \[\frac{1}{100}\times \frac{IA\lambda }{hc}\] \[=\frac{1}{100}\frac{1\times {{10}^{-4}}\times 300\times {{10}^{-9}}}{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}=1.5\times {{10}^{12}}\]
