Question

An electric dipole consists of two equal and opposite point charges ±q separated by distance 2a. Its dipole moment magnitude is

Accepted Answer

C. {'text': 'p = q × 2a', 'label': 'C'}

1. Dipole moment p is defined as charge × separation.
2. For dipole of ±q separated by 2a: p = q × (2a) = 2aq.
3. Direction of p is from −q to +q.
4. SI units: coulomb-metre (C·m).
