Concept:Hydrostatic pressure increases with depth. Water exits a hole with velocity given by Torricelli’s law: v=2gh​, where h is the depth of the hole below the water surface. Both the force of efflux and the horizontal range depend on this velocity and the hole’s height above the ground.Explanation:- At the lowest hole, depth is greatest, so pressure and exit velocity are highest. Hence water comes out with the greatest force. → Statement (a) is true.- At the highest hole, depth is smallest, so pressure and exit velocity are lowest. → Statement (b) is false; (c) and (f) are also false.- Horizontal distance of the water stream depends on exit velocity and height from ground. The lowest hole has higher velocity but lower height; these factors combine to give it the maximum range. → Statement (d) is true.- The highest hole has lower velocity and greater height, resulting in a shorter range. → Statement (e) is false.Thus, only (a) and (d) are correct.Answer:B. (a) and (d)
