An air bubble of radius 1mm is formed inside water at a depth 10m below free surface (where air pressure is `10^5 N/m^2)`. The pressure inside the bubble is – (Surface tension of water = `7 x× 10^(–2) N//m)`

A small air bubble of radius 0.1 mm is situated at a depth of 10 m below the free surface of water .The external pressure on the bubble will be

An air bubble of radius 1 mm is located at a depth of 20 cm below water level. The excess pressure inside the bubble above the atmospheric pressure is [Given, the surface tension of water is "0.075 Nm"^(-1) and density is "1000 kg m"^(-3) ]

A bubble of radius 10 cm is formed with a solution that has surface tension 40xx10^-3 N//m . What is the excess pressure inside the bubble in N//m^2 ?

A small air bubble of radius 0.1mm is situated at a depth of 20 m below the free surface of water . The external pressure on the bubble will be (Atm. Pressure = 10^5N//m^2,g=10m//s^2)

A small air bubble of radius 0.1mm is situated at a depth of 20 m below the free surface of water . The external pressure on the bubble will be (Atm. Pressure = 10^5N//m^2,g=10m//s^2)

A spherical air bubble of radius r is formed in water. If T be the surface tension of water, the excess pressure inside the bubble is
