A capillary tube is vertically immersed in water, water rises upto a height 'h ₁ '. When the whole arrangement is taken to a depth 'd' in a mine, the water level rises upto height ^ h₂ '. The ratio h ₁ / h ₂ is ( R = radius of earth )

Options

  1. A(1+ 2 ~d R )
  2. B(1- d R )
  3. C(1+ d R )
  4. D(1- 2 d R )

Correct answer

B. (1- d R )

Step-by-step solution

aligned & h= 2 T r g & h 1 g & h₁ h₂ = g₂ g₁ =1- d R aligned
