JEE MainPhysicsProperties of MatterMCQ+4 / −1
Water from a tap emerges vertically downwards with an initial speed of 1.0 ms–1 . The cross-sectional area of the tap is 10–4 m2. 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–2)
  1. A
    5 × 10–4 m2
  2. B
    2 × 10–5 m2
  3. C
    5 × 10–5 m2
