Torque on Electric Dipole - Physics Special Cases

Today we study the special cases of torque on an electric dipole. The general formula

is defined as torque equals p e sine theta. In case one,

the dipole is parallel to the field, making torque zero. Case two:

at ninety degrees, the dipole experiences its maximum possible torque. Case three:

when anti-parallel at one eighty degrees, the torque is again zero. Maximum torque occurs

at ninety degrees, while zero torque occurs at equilibrium. Make sure to save this video
