Electric Potential and Capacitance · Potential

Three small identical bubbles of water having same charge on each coalesce to form a bigger bubble. Then the ratio of the potentials on one initial bubble and that on the resultant bigger bubble is :
  1. (1)1:31/31 : 3^{1/3}
  2. (2)1:22/31 : 2^{2/3}
  3. (3)32/3:13^{2/3} : 1
  4. (4)1:32/31 : 3^{2/3}
