Eight identical spherical raindrops are each at a potential V, relative to the potential far away.They coalesce to make one spherical raindrop whose potential is:

Question

Quizplus · Accepted Answer

When the raindrops coalesce, the volume of the new drop is the sum of the volumes of the original drops. Since potential is proportional to charge and inversely proportional to radius, and the radius of the new drop is larger, the potential increases. The potential of the new drop is 4 times the original potential.
