Question

what is the dimensional formula of electric dipole moment

Answer 1

simply break it 's formula & then put their dimensional formula separately. i.e; [p]= [q x d ]
=[q] [d] { where d= distance of separation b/w them}
= [c] [m]
= [ampere x sec] [m]
= [A1T1L1]

Answer 2

Explanation:

Two equal and opposite charges placed at some distance is called dipole. Electric dipole moment is the measure of total polarity. If the charges are +q and -q and they are separated by a distance of 2a. Then electric dipole moment is given by :

$p=q\times 2a$

The SI unit of charge q is coulomb. Its dimensional formula is [C]

The SI unit of charge a i.e. length is meter. Its dimensional formula is [m]        

So, the dimensional formula of electric dipole moment is [LC].
