A) 8 cm
B) 16 cm
C) Between 8 cm and 16 cm
D) Less than 8 cm
Correct Answer: C
Solution :
m = ± 3, using \[m=\frac{f}{f+u}\] For virtual image \[3=\frac{f}{f-8}\] .....(i) For real image \[-\,3=\frac{f}{f-16}\] .....(ii) Solving (i) and (ii) we get \[f=12\,cm\]You need to login to perform this action.
