If a drop of water of radius 0.1 cm is broken up into a million droplets all of the same size , then the energy expended in the process will be

A

`197 pi ` erg

B

`297 pi` erg

C

`397 pi` erg

D

` 497 pi ` erg

Text Solution

Verified by Experts

The correct Answer is:
B
`dE = 4piR^(2)T (n^(1//3)-1)`
` = 12.56 xx10^(-2) xx 75 xx 99 = 297` erg
