The excess pressure inside a spherical drop of liquid is .
(b)
The excess pressure inside a spherical soap bubble is .
(c)
The excess pressure inside a cylindrical drop of liquid is .
(d)
Only (A) and (B)
Correct answer: (b)  (c) 
Solution: 
The spherical liquid have only one surface which is applying force 


Inside soap bubble, there are two free surfaces
So,    
         

Inside cylindrical drop of liquid. There are two surfaces one is having radius and another is of radius 
The generalized result of pressure.
