A dipole is centered at the origin of a coordinate system, and a small charged sphere is some distance away along the perpendicular bisector of the dipole. The particle carries a uniformly distributed charge of -3.0 nC
, and experiences a 200 nN
electric force in the positive y
direction.
(a) If the dipole charge is 10 nC
and the dipole separation is 20 mm
, how far away from the dipole is the sphere?
Express your answer with the appropriate units.
(b) How is the dipole moment oriented?
