Question

1.
64 water drops having equal charges combine to form one bigger drop. The capacitance of the bigger drop, ascompared to that of the smaller drop will be -
a) 8 times
b) 16 times
C) 64 times
d) 4 times​

Answer 1

Answer:

option d

Explanation:

Capacitance of the drop is directly proportional to radius. Therefore, capacitance of the big drop will be 4 times the small drop
