Calculate the energy spent on spraying a drop of mercury of 1 cm radius into 10^6 droplets all of same radius. surface tension of mercury is 0.035n/m

ANS : .Energy spent on spraying =

Explanation:

Given:

Thus, volume is conserved.

i.e ,

Where ,

Initial energy

Final energy

∴  .Energy spent on spraying =

ANS : .Energy spent on spraying =
