Q.

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 stream, 0.15 m below the tap would be:  (Take g = 10 ms–2)

  1. A

    1 × 10–5 m2

  2. B

    5 × 10–5 m2

  3. C

    5 × 10–4 m2

  4. D

    2 × 10–5 m2
