A) 3/2
B) 2/3
C) 4/3
D) 3/4
Correct Answer: A
Solution :
Velocity of fish is \[u=2m{{s}^{1}}\] Velocity of bird (w. r. t fish) is \[V=4m{{s}^{1}}\] Refractive index of water \[\mu =\frac{4}{3}\]actual velocity of bird\[=\frac{V-\mu }{\mu }=\frac{4-2}{\frac{4}{3}}=\frac{3}{4}\times 2=\frac{3}{2}\]You need to login to perform this action.
