A straight rod OABCD is strapped on to the end of a straight hose pipe H with 'A' at the nozzle of the pipe (figure). Strings are ties to the rod at B,C and D and are allowed to drop down vertically. The lengths of the strings at B, C and D to just touch the stream of water, streaming out of the hose pipe from its nozzle, are in the ratio |

Answer» `(1)/(AB):(1)/(BC):(1)/(CD)` `l=(1)/(2)GT^(2)=(1)/(2)g((Ax)/(v))^(2)` `l_(1):l_(2):l_(3)=AB^(2):AC^(2):AD^(2)` |
