A water drop is divided into 8 equal droplets. The pressure difference between the inner and outer side of the big drop will be

A

will be the same as for smaller droplet

B

will be half of that for smaller droplet

C

will be `1//4^("th")` of that for smaller droplet

D

will be twice of that for smaller droplet

Text Solution

Verified by Experts

The correct Answer is:
B
`P=(2T)/(R )`,
`(P_(1))/(P_(2))=(R_(2))/(R_(1))(because (4)/(3)piR^(3)=8xx(4)/(3)pir^(3)rArr R=2r)rArr (P_("big"))/(P_("small"))=(r )/(R )`
