A bucket of height 20 cm is placed under a tap such that water flows into the bucket at a constant rate of 100 cm3/s. There is a small hole in the bucket of cross-sectional area of 1 cm2 at height of 3 cm from the bottom. Area of hole is very small as compared to area of the bucket. Find the maximum height (in cm ) above the bottom upto which the water is filled in the bucket. (Take g = 10 m/s2 )

Q = a√2gh
h = Q²/ (a² × 2g) = (10? )²/ (10? × 2 × 10) = 5 cm
Height above the ground = 3 cm + 5 cm = 8 cm
