`1mm Hg` pressure is equivalent to one torr and one torr is equivalent to `133.3N//m^(2)`. The atomospheric presue in mm of `Hg` pressure is

A

`70 mm`

B

`760 mm`

C

`3.76 mm`

D

none of these

Text Solution

Verified by Experts

(b) `1atm-1.013xx10^(5)N//m^(2)`
`:'133.3N//m^(2)=1mm` of `Hg`
`:.1 N//m^(2)=1/(133.3)mm` of `Hg=1.013xx10^(5)N//m^(2)`
`=1/(133.3)xx1.013xx10^(5)` of `Hg=760 mm` of `Hg`
