A)
B)
C)
D)
Correct Answer: A
Solution :
Since \[\frac{1}{f}=\frac{1}{v}+\frac{1}{u}\] Þ \[\frac{1}{v}=-\frac{1}{u}+\frac{1}{f}\] Putting the sign convention properly \[\frac{1}{(-v)}=\frac{-1}{(-u)}+\frac{1}{(-f)}\] Þ \[\frac{1}{v}=-\frac{1}{u}+\frac{1}{f}\] Comparing this equation with y = mx + c Slope = m = tanq = ? 1 Þ q = 135° or ? 45° and intercept \[C=+\frac{1}{f}\]You need to login to perform this action.
