Eight identical spherical drops, each having a potential of 9V, are combined together to form a single large drop. The potential of this large drop will be:
36 V
When n identical drops combine, the potential of the new large drop is given by:
Vnew = n1/3 Vsmall.
Given n = 8 and Vsmall = 9V:
Vnew = 81/3 × 9V = 2 × 9V = 36V.
Thus, the correct answer is (c).
