A) 6.00 cm
B) 7.75 cm
C) 9.25 cm
D) 11.00 cm
Correct Answer: D
Solution :
\[L={{v}_{0}}+{{u}_{e}}=\frac{{{u}_{0}}{{f}_{0}}}{({{u}_{0}}-{{f}_{0}})}\,\,+\,\,\frac{{{f}_{e}}D}{{{f}_{e}}+D}\] \[\Rightarrow \,\,\,\,L=\frac{2\times 1.5}{(2-1.5)}+\frac{6.25\times 25}{(6.25+25)}\,\,=\,\,11\,\,cm\]You need to login to perform this action.
