Physics Question from JEE Main 2025 · 2 April, Shift 2

Two water drops each of radius rr coalesce to form a bigger drop. If TT is the surface tension, the surface energy released in this process is:

  • A

    4πr2T[2−22/3]4\pi r^2 T \left[ 2 - 2^{2/3} \right]

  • B

    4πr2T[2−21/3]4\pi r^2 T \left[ 2 - 2^{1/3} \right]

  • C

    4πr2T[1+2]4\pi r^2 T \left[ 1 + \sqrt{2} \right]

  • D

    4πr2T[2−1]4\pi r^2 T \left[ \sqrt{2} - 1 \right]
