An electric dipole consists of two opposite charges of magnitude `1//3xx10^(-7)C`, separated by 2 cm. The dipole is placed in an external field of `3xx10^(7) NC^(-1)`. What maximum torque does the electrc field exert on the dipole ?

Text Solution

Verified by Experts

Torque = pE `sin theta`
For maximum value of torque, `sin theta=1`
`:." ""maximum torque"=pE`
`=(0.2xx10^(-6)xx2xx10^(-2))(2xx10^(5))`
`=8xx10^(-4)` Nm
