    Two spherical bubbles are in contact with each other internally as shown. The radius of curvature of the common surface is R, then -

    A)  \[R>{{R}_{1}}\]                     

    B)  \[{{R}_{1}}>R>{{R}_{2}}\]

    C)  \[R<{{R}_{2}}\]                     

    D)  \[R={{R}_{1}}\]

    Correct Answer: C

    Solution :

       Pressure difference is largest between atmosphere and smaller bubbles. Hence radius of curvature (R) is smallest.
