A water drop falls in air with a uniform velocity. Find the difference between the curvature radii of the drops surface at the upper and lower points of the drop separated by the distance h = 2.3 mm.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
The radius of curvature of the drop is 
at the upper end of the drop and 
at lower end. Then
the pressure inside the drop is 
at the top 
at the bottom end. Hence
To a first approximation
