Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other.
Explanation:
It is given that,
An electric dipole consists of charges +2e and -2e separated by 0.82 nm
Charge, 
Distance between charges, 
Electric field strength, 
(a) The magnitude of the torque on the dipole is given by :

When dipole moment is parallel to the electric field, 


(b) When the dipole is perpendicular to the electric field, 

(Since, p = q × d)


(c) When the dipole moment is anti parallel to the electric field, 

Since, 

Hence, this is the required solution.
