JEE Main 2019 Physics question

Water from a tap emerges vertically downwards with an initial speed of 1.0 ms. The cross-sectional area of the tap is m. Assume that the pressure is constant throughout the stream of water and that the flow is streamlined. The cross-sectional area of the stream, 0.15 m below the tap would be: (Take g = 10 ms)

• (A) m
• (B) m
• (C) mCorrect
• (D) m
