What is fluid statics? $OR$ What is fluid mechanics?
(N/A) Fluid mechanics is the branch of physics that deals with the behavior of fluids (liquids and gases) at rest and in motion. It is broadly divided into two main branches:
$1$. Fluid Statics: This is the study of fluids at rest. It focuses on the properties of fluids in equilibrium,such as pressure distribution and buoyancy,where there is no relative motion between fluid particles.
$2$. Fluid Dynamics: This is the study of fluids in motion. It deals with the forces acting on fluids and the resulting flow patterns,including concepts like viscosity,turbulence,and Bernoulli's principle.

View SolutionWhen a soap bubble of radius $0.2 \ mm$ is charged,it experiences an outward electrostatic pressure of magnitude $\frac{\sigma^2}{2 \varepsilon_0}$,where $\sigma = 20 \ \mu C \ m^{-2}$ is the surface charge density. If the excess pressure inside the soap bubble due to the surface tension is same as this electrostatic pressure,then the surface tension of the soap solution is (Given: $\varepsilon_0 = 8.85 \times 10^{-12} \ C^2 \ N^{-1} \ m^{-2}$)
$A$ uniform meter scale is supported at its $20 \ cm$ mark. $A$ body suspended from the $10 \ cm$ mark keeps the scale horizontal. However,the scale becomes unbalanced if the body is completely immersed in water. To regain the balance,the body is shifted to the $8 \ cm$ mark. Therefore,the specific gravity of the material of the body is
