Consider an electric dipole whose dipole moment (a vector pointing from the negitive charge to the positive charge) is oriented at angle with respect to the y axis. There is an externalelectric field of magnitude (independent of the field produced bythe dipole) pointing in the positive y direction. The positive and negative ends of the dipole have charges and , respectively, and the two charges are a distance apart. The dipole has a moment of inertia about its center of...

A charge configuration with two
charges of opposite sign but the same magnitude, q, and a
separation distance, d, is called an electric dipole. The
electric dipole moment, or EDM, is a vector, p,
with a magnitude p = qd and a direction from the
negative charge towards the positive charge. When such a dipole is
placed in a region of electric field, it will experience a torque
which depends upon the angle, θ, between the directions of the EDM,...
What is the magnitude of the dipole moment for the two charges, q, spaced a distance s apart? Express your answer with the appropriate units. Review An electric dipole is formed from two charges, ±q, spaced a distance s apart. The distance s is small compared to 10 cm. The dipole is at the origin, and the dipole moment p points in the y- direction. The electric field strength at the point P : (x, y ,(0 cm, 10 cm)...
