JEE MainPhysicsProperties of MatterMCQ+4 / −1
Two water drops each of radius ' rrr' coalesce to form a bigger drop. If 'TTT ' is the surface tension, the surface energy released in this process is :
  1. A
    4πr2 T[2−21/3]4 \pi \mathrm{r}^2 \mathrm{~T}\left[2-2^{1 / 3}\right]4πr2 T[2−21/3]
  2. B
    4πr2 T[1+2]4 \pi \mathrm{r}^2 \mathrm{~T}[1+\sqrt{2}]4πr2 T[1+2​]
  3. C
    4πr2 T[2−22/3]4 \pi \mathrm{r}^2 \mathrm{~T}\left[2-2^{2 / 3}\right]4πr2 T[2−22/3]
