Water rises upto a height 'h' in a capillary tube on the surface of the earth. The value of ' h ' will increase if the experimental setup is kept in [ g = acceleration due to gravity]

Options

  1. Aa lift going upward with a certain acceleration.
  2. Ba lift going down with acceleration
  3. Caccelerating train.
  4. Da satellite rotating close to earth.

Correct answer

B. a lift going down with acceleration

Step-by-step solution

(D) h= 2 T r g h 1 g For a lift going down with acceleration a , the effective value of g is g^ =g-ag^ =g-a g ^ < g h will increase.
