Question

A capillary of the shape as shown is dipped in a liquid. Contact angle between the liquid and the capillary is 0 to the power of 0 end exponent and effect of liquid inside the meniscus is to be neglected. T is surface tension of the liquid, r is radius of the meniscus, g is acceleration due to gravity and r is density of the liquid then height h in equilibrium is

  1. greater than fraction numerator 2 T over denominator r rho g end fraction    
  2. equal to fraction numerator 2 T over denominator r rho g end fraction    
  3. less than fraction numerator 2 T over denominator r rho g end fraction    
  4. of any value depending upon actual values    

The correct answer is: less than fraction numerator 2 T over denominator r rho g end fraction

A square box of water has a small hole located in one of the bottom corner. When the box is full and placed on a level surface, complete opening of the hole results in a flow of water with a speed V subscript 0 end subscript , as shown in figure (A). When the box is still half empty, it is tilted by 45 to the power of ring operator end exponent so that the hole is at the lowest point. Now the water will flow out with a speed of
