Question:medium
A mercury drop of radius 1 cm is sprayed into \(10^6\) drops of equal size.
The energy expressed in joules is (surface tension of mercury is \(460 \times 10^{-3} \, \text{N/m}\)).
A mercury drop of radius 1 cm is sprayed into \(10^6\) drops of equal size.
The energy expressed in joules is (surface tension of mercury is \(460 \times 10^{-3} \, \text{N/m}\)).
Show Hint
Surface energy change depends only on change in surface area:
E = T Δ A
Breaking droplets increases surface area significantly.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
