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 .

Correct answer

0

Step-by-step solution

R = 2 g h × ( 12 - h ) × 2   g 4   h ( 12 - h ) = R For maximum R d R d h = 0 ⇒ h = 6   m
