A) \[0.436\times {{10}^{18}}\]
B) \[0.436\times {{10}^{17}}\]
C) \[0.775\times {{10}^{15}}\]
D) \[0.775\times {{10}^{16}}\]
Correct Answer: C
Solution :
For photoelectric effect, \[e{{V}_{0}}=hv\] \[\Rightarrow \] \[v=\frac{e{{V}_{0}}}{h}\] \[\therefore \] \[v=\frac{1.6\times {{10}^{-19}}\times 3.2}{6.6\times {{10}^{-34}}}\]You need to login to perform this action.
