A certain number of spherical drops a liquid of radius r coalesce to form a a single drop of radius R and volume V . If 'T' is the surface tension of the liquid , then:

A

Energy = `4VT[1/r-1/R]` is released

B

Energy = `3VT[1/r-1/R]` is absorbed

C

Energy = `3VT[1/r-1/R]` is released

D

Energy is neither released not absorbed.
