Question

For the configuration with +0.25 μC at (0, 0, −15 cm) and −0.25 μC at (0, 0, +15 cm), the direction of the dipole moment is:

पर्याय

• Along the −Z axis

• Along the +Z axis

• In the XY plane

• Along the +X axis

Answer 1

The dipole moment direction is defined as pointing from the negative charge to the positive charge. Here, the negative charge is at +15 cm (top, +Z), and the positive charge is at −15 cm (bottom, −Z). Therefore, the dipole moment points from the negative charge (at +Z) toward the positive charge (at −Z), which is along the −Z axis.
