An isolated and charged spherical soap bubble has a radius 'r' and the pressure inside is atmospheric. If 'T' is the surface tension of soap solution, then charge on drop is:

An isolated and charged spherical soap bubble has a radius r and the pressure inside is atmospheric. IfT is the surface tension of soap solution, then charge on drop is Xpi sqrt(2r T epsi _(0)) then find the value of X.

Excess pressure inside a soap bubble of radius r and surface tension T is

What is the excess of pressure inside a soap bubble of radius 3cm if the surface tension of the soap solution is 30 dyn/cm ?

Calculate the excess inside a soap bubble of radius 5mm, given surface tension of soap solution 30 dyne/cm.

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

A soap bubble of radius r is formed inside another soap bubble of radius R (gt r) . The atmospheric pressure is P_(0) and surface tension of the soap solution is T. Calculate change in radius of the smaller bubble if the outer bubble bursts. Assume that the excess pressure inside a bubble is small compared to P_(0) .

The excess pressure inside a soap bubble of radius R is (S is the surface tension)
