1. The problem statement, all variables and given/known data Q15. 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: A. V/8 B. V/2 C. 2V D. 4V E. 8V 2. Relevant equations V = sum( Vi ) 3. The attempt at a solution OK so if you just sum the potentials you get 8V right? But the answer's D, 4v. Can someone make sense of this to me, please? I don't get what's cutting the value in half.
