Water is filled in uniform container of area of cross section A. A hole of cross section area (a lt lt lt A)is made in the container at a height of 20m above the base. Water stream out and hits a small block on surface at some distance from container. Block is moved on surface in such a way that stream always hits the block. The initial velocity of the block (in m//s) will be if (a)/(A)=(1)/(20).(g=10m//s^(2)) |

Answer» `t=sqrt((2xx20)/(10))=2sec` `S=2sqrt(2g(H-20))` `S^(2)=80 (H-20)` `S^(2)=80H-1600` `(ds)/(DT)=1m//s`
