Solution

The correct option is B 10
Speed at which water flows out from the orifice= $\sqrt{2 \times g \times h} = \sqrt{5 \times 2 \times 10}$ =10 m/s
where h is the height of water in the tank.

The initial speed with which water flows out from the orifice in ms−1 is (g = 10ms−2):

The correct option is B 10Speed at which water flows out from the orifice= √2×g×h=√5×2×10 =10 m/swhere h is the height of water in the tank.
