A small liquid drop of radius R is divided into 27 identical liquid drops. If the surface tension is T, then the work done in the process will be:

Question

Accepted Answer

Correct answer: A. (a) Volume constant 43 R^3=27 43 r^3 R^3=27r^3 R=3r r= R3 r^2= R^29 Work done =T A =27 T (4 r^2 )-T4 R^2 =27 T4 R^29-4 R^2 T =8 R^2 T
