An electrtic dipole with dipole moment `4xx10^(-9) C m` is aligned at `30^(@)` with the direction of a uniform electric field of magnitude `5xx10^(4) NC^(-1)`. Calculate the magnitude of the torque acting on the dipole .

Explanation

The torque on the electric dipole kept inside the electric field is : `vectau=vecpxxvecE rArr tau = pEsin theta `
`tau =(4xx10^(-9))(5xx10^4) (sin 30^@)=1xx10^(-4)` N m
