Homework Statement
A conducting bubble of radius a, thickness t(t<<a) has potential V. Now the bubble collapses into a droplet. Find the potential of the droplet.
Homework Equations
Potential at the surface of bubble=##V##=##\frac{Kq}{a}##
The Attempt at a Solution
Potential at the surface of bubble=##V##=##\frac{Kq}{a}##
bubble collapses into droplet.Let the radius of droplet to be R. Volume of droplet should be same as of bubble.
volume of droplet=##\frac{4}{3}####πR^3##
volume of bubble =##\frac{4}{3}####πa^3##
##\frac{4}{3}####πR^3##=##\frac{4}{3}####πa^3##
Am I right till here?I don't think so,because I have not used thickness t anywhere.
