WebIf the radius and surface tension of a spherical soap bubble be r and T respectively. Find the charge uniformly distributed over the outer surface of the bubble, is required to double radius. (Given that atmospheric pressure is P0 and inside temperature of the bubble during expansion remains constant.) Class 11 >> Physics http://hyperphysics.phy-astr.gsu.edu/hbase/surten2.html
WebConsider a free-body diagram for a half-sphere of a particle (or soap bubble) as shown above: radius is r, and circumference (at equator) is 2п r. ∆P is the internal pressure relative to the outside pressure. γ is surface energy. Surface tension force acts parallel to the particle’s (bubble's) surface, and is distributed around WebApr 24, 2024 · Best answer Consider a soap bubble of radius R and surface tension T. There are two free surfaces of soap bubble. Due to surface tension the molecules on the surface film experience the net force in inward direction normal to the surface. Therefore there is more pressure inside than outside.
