JEE Main 2026 Physics question
A cylindrical vessel of 40 cm radius is completely filled with water and its capacity is 528 dm³ (dm : decimeter). The vessel is placed on a solid block of exactly same height as vessel. If a small hole is made at 70 cm below the top of water level, then horizontal range of water falling on the ground in the beginning is cm.
Answer: (B)
Solution
Vessel height=528 dm³/(π·4² dm²)=10.5 dm=105 cm (with π=22/7). The top of the water is 105+105=210 cm
