8000 identical water drops are combined to form a big drop then the ratio of the final surface energy to the initial surface energy of all the drops together is

A

`20:1`

B

`1:19`

C

`1:20`

D

`19:1`

Text Solution

Verified by Experts

The correct Answer is:
C
`(E_(2))/(E_(1)) = 1/(n^(1//3)) = 1/(8xx 10^(3))^(1//3) = 1 : 20 `
