A sample of HCl gas is placed in an electrical field of `3 xx 10^(4)NC^(-1)`. The dipole moment of each HCl molecule is `6 xx 10^(-30) C -m`. The maximum torque that can act on a moleucle is

A

`2 xx10^(-34) C^2 N^(1) m`

B

`2 xx10^(-34) Nm`

C

`18 xx10^(-26) Nm`

D

`0.5 xx10^(34)C^(-2) N^(-1) m^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`tau_(max) =pE`
`implies tau_(max) = 6 xx10^(-30) xx3 xx10^4`
`=18 xx10^(-26) Nm`
