When a soap bubble is charged :-

A soap bubble is charged to a potential 12 V. If its radius is doubled, the potential of the bubble becomes

The excess pressure inside a soap bubble is thrice the excess pressure inside a second soap bubble. What is the ratio between the volume of the first and the second bubble?

The excess pressure inside a soap bubble is thrice the excess pressure inside a second soap bubble. What is the ratio between the volume of the first and the second bubble.?

The excess pressure inside a soap bubble is thrice the excess pressure inside a second soap bubble. What is the ratio between the volume of the first and the second bubble?

A charged soap bobbe having surface charge density sigma and radius r. If the pressure inside and outsides the soap bubble is the same, then the surface tension of the soap solution is

A charged soap bobbe having surface charge density sigma and radius r. If the pressure inside and outsides the soap bubble is the same, then the surface tension of the soap solution is

The radius of soap bubble is increased to double its initial size. Calculate the percentage change in the excess pressure inside the soap bubble.
