A tank with a small hole at the bottom has been filled with water and kerosene (specific gravity 0.8 ). The height of water is 3 m and that of kerosene 2 m . When the hole opened the velocity of fluid coming out from it is nearly: (take g = 10 ms⁻² and density of water 10³ kg m⁻³)
a. 9.6 m/s
b. 8.5 m/s
c. 7.6 m/s
d. 10.7 m/s
