The surface energy of a liquid drop is E...

The surface energy of a liquid drop is `E`. It is sprayed into `1000` equal droplets. Then its surface energy becomes

A

E

B

10 E

C

100 E

D

1000 E

Text Solution

Verified by Experts

The correct Answer is:
B
` Delta E = = E_(1)(n^(1//3)-1) = E_(i) xx9`
` E_(f) -E_(i) = 9E_(i)`
` :. E_(f) = 10 E `
