Question

If 'Q' is the magnitude of charge and 'r' is the distance between the centres of positive and negative charges then dipole moment (µ) is given by ______.

Options

• μ = Q × r

• μ = Q + r

• μ = Q - r

• μ = `"Q"/"r"`

Answer 1

If 'Q' is the magnitude of charge and 'r' is the distance between the centres of positive and negative charges then dipole moment (µ) is given by μ = Q × r.

Explanation:

Dipole moment (µ) is the product of the magnitude of the charge (Q) and the distance between the centres of positive and negative charge (r).

∴ μ = Q × r
