A) \[\frac{d}{2}\]
B) \[d\]
C) \[\frac{d}{4}\]
D) \[\frac{d}{3}\]
Correct Answer: C
Solution :
As is clear from the figure that triangles ACI and EBI are similar. Using similarity rule, we get \[\therefore \]\[\frac{h}{d/2}=\frac{f}{2f},\]where \[h=BE\] \[\Rightarrow \]\[\frac{2h}{d}=\frac{1}{2}\]or \[h=d/4\] Hence, the correction option is (c).You need to login to perform this action.
