A dielectric develops a _____in an external electric field.
net dipole moment
zero dipole moment
zero charge separation
positive charge
Due to charge separation, a net dipole moment is created.
An electric dipole ( dipole moment p) is placed at a radial distance r>>a ( Where a is dipole length) from an infinite line of charge having linear charge density +λ. dipole moment vector is aligned along the radial vector →r force experienced by the dipole is:-
