MHT CET 2025 19th April Morning Shift | Fluid Mechanics Question 18 | Physics

When a big drop of water is formed from ' $n$ ' small drops of water, the energy loss is ' 3 E ' where ' $E$ ' is the energy of the bigger drop. The radius of the bigger drop is ' R ' and that of smaller drop is ' $r$ ' then the value of ' $n$ ' is

$\frac{2 R^2}{r}$

$\frac{4 R^2}{r^2}$

$\frac{4 R}{r}$

$\frac{4 R}{r^2}$
