A conducting soap bubble having a radius a, thickness 
is charged to a potential V. If now, the bubble collapses and forms a droplet, then the potential of the droplet is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Let q be the charge on the bubble, then
Let after collapsing, the radius of droplet becomes R, then equating the volume, we have
Now, potential of droplet will be
Substituting the values, we have or
