Force due to Fluid on Surface

Surface Tension: Force due to Surface tension| Pressure difference across a spherical surface|Excess pressure in liquid drop| air bubble| soap bubble

Surface Tension: Force due to Surface Tension | Pressure difference across a Spherical Surface (excess pressure in liquid drop, air bubble, soap bubble) | Surface energy

The force of surface tension acts tangentially to surface whereas the force due to air pressure perpendicularly on the surface. How is then due to excess pressure inside a bubble bal force due to the surface tension ?

The force due to surface tension is

Force Exerted by Fluid on Body

Assertion: A needle placed carefully on the surface of water may float. Reason: A needle placed carefully on the surface of water may float due to the surface tension as upward forces due to surface tension balances the weight of the needle.

A body weighs 64 N on the surface of Earth. What is the gravitational force on it due to the earth, at a height equal to half the radius of Earth ? Acceleration due to gravity on the surface of Earth is 10 m s^(-2) .

If the length of a needle floating on water is 2 cm then the additional force due to surface tension required to pull the needle out of water will be
