A conducting bubble of radius a, thickness t (<< a) has potential V. Now the bubble collapses into a droplet. The potential of the surface of droplet will be :-

G1 Physics · Accepted Answer

Step 1: In electrostatic equilibrium, E = 0 inside a conductor and the conductor is an equipotential. Surface charges adjust so the boundary condition field just outside·𝐧 = σ/ε₀ is satisfied. Step 2: For connected conductors set their potentials equal; for sheets use electrostatic pressure p = ε₀E²/2 when appropriate. Step 3: Apply charge conservation and the given geometry. Final: Option C. In this specific setup, apply the calculation to: A conducting bubble of radius a, thickness t (<&l…
