A person of height 1.65 ~m is standing upright. The additional external force required by blood vessel of length 1 ~cm , diameter 1 ~mm at feet to balance the pressure compared to similar blood vessel in head is (Density of blood =1.1 10^3 ~kg ~m ⁻³, ~g =10 ~ms ⁻² )

Options

  1. A0.57 ~N
  2. B5.7 ~N
  3. C1.85 ~N
  4. D3.14 ~N

Correct answer

A. 0.57 ~N

Step-by-step solution

Pressure difference p = gh and force exerted aligned & F = P . A = gh .2 r ( r + h ) & =1.1 10^3 10 1.65 2 22 7 0.5 10⁻³ & (0.5 10⁻³+ h ) & =18150 2 22 7 0.5 10⁻³ (0.5 10⁻³+10 . & .10⁻³ ) & F 0.57 ~N . aligned
