Q10.In a cylindrical water tank, there are two small holes A and B on the wall at a depth of h1 , from the surface of water and at a height of h2 from the bottom of water tank. Surface of water is at height of h2 from the bottom of water tank. Surface of water is at heigh H from the bottom of water tank. Water coming out from both holes strikes the ground at the same point S . Find the ratio of h1 and h2 (1) Depends on H (2) 1 : 1 (3) 2 : 2 (4) 1 : 2
What This Question Tests
This question requires combining Torricelli's law for efflux velocity with projectile motion principles to find the condition for water jets to strike the ground at the same point.

9.3 — A Tank Is Filled With Water To A Height Of 12.5 Cm. The Apparent
Physics Class 12 · Chapter 9
9.3 A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?
