The limbs of a manometer consist of uniform capillary tubes of radii are `10^(-3)&7.2xx10^(-4)`m find out the correct pressure difference if the level of the liquid in narrower tube stands 0.2 m above that in the broader tube. (density of liquid `=10^(3)kg//m^(3)`, surface tension `=72xx10^(-3)N//m`)

A

`930 Nm^(-2)`

B

`1860Nm^(-2)`

C

`3660 Nm^(-2)`

D

`1530 Nm^(-2)`
