Fluid Statics or Hydrostatic(Liquid at Rest)-1

The direction of the force exerted on a surface by a liquid at rest is

The "______" exerted by a liquid at rest per unit area normal to the surface in contact with the liquid is called pressure.

why does the free surface of a liquid at rest behave like a stretched elastic membrane?

A liquid cannot withstand a shear stress. How does this impty that the surface of a liquid at rest must be level, i.e., normal to the gravitational force?

...........is the property by virtue of which the free surface of the liquid at rest behaves like a stretched elastic membrane tending to contract to occupy minimum surface area.

Surface tension is the property of a liquid by virtue of which the free space of the liquid at rest tends to have minimum area and as such it behaves as if covered with a stretched membrane. It is measured as the force acting an unit length of a line imagined to be drawn tangentially anywhere on the free surface of liquid at rest. It acts at right angles to this line on both sides and along the tangent to the liquid surface. When a razor bladed floats on water, then the force of surface tension acts on the circumference of the blade acting tangentially to the liquid surface : (a) True (b) False

Raindrops are spherical in shape because each drop tends to acquire maximum surface area : (a) True (b) False

The iron needle will floats on clean water but sink when some detergent is added to this water (a) True (b) False
