The water is filled up to a height of 12 m in a tank having vertical sidewalls. A hole is made in one of the walls at a depth h below the water level. The value of h for which the emerging stream of water strikes the ground at the maximum range is _____ m.

Solution

R=2gh×(12-h)×2 g

4 h(12-h)=R

For maximum R

dRdh=0

⇒h=6 m
