Surface charge density of soap bubble
WebA soap bubble is an extremely thin film of soap or detergent and water enclosing air that forms a hollow sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their … WebWhen a soap bubble of radius 0.2 mm is where σ=20 μ Cm -2 is the surface charge density. If the excess pressure inside the soap bubble due to the surface tension is same as this electrostatic pressure, then the surface tension of the soap solution is (ε0=8.85 × …

WebHard Solution Verified by Toppr Correct option is C) The bubble will expand because the charged particles uniformly distributed on it causes them to repel each other due to the electrostatic force. This will happen to both positive and negatively charged bubbles because of the charge on it. http://www1.phys.vt.edu/bubble/properties-of-bubbles.html
WebThe above explanation only holds for bubbles of one medium submerged in another medium (e.g. bubbles of gas in a soft drink); the volume of a membrane bubble (e.g. soap bubble) will not distort light very much, and one can only see a membrane bubble due to thin-film diffraction and reflection .
