A) \[\frac{hv}{H+h}\]
B) \[\frac{Hv}{H-h}\]
C) \[\frac{H+h}{Hv}\]
D) \[\frac{\left( H-h \right)}{Hh}\]
Correct Answer: B
Solution :
as \[\Delta \text{LOS}\]and \[\Delta \text{MPS}\] are similar so, \[\frac{H}{x}=\frac{h}{x-y}\Rightarrow \left( H-hz \right)x=Hy\] \[\Rightarrow \left( H-h \right)\frac{dx}{dt}=H\frac{dy}{dy}=Hv\] \[\Rightarrow {{V}_{S}}=\frac{Hv}{H-h}\]You need to login to perform this action.
