184 Chapt. 23 The Electric Field d) Assuming the motion of the electron is uniform circular motion, what is the electron speed v ? What is the ratio v/c , where c is the speed of light? Recall v/c is conventionally designated β in relativity. 023 qfull 00530 2 3 0 moderate math: simple electric dipole electric field 5. A simple electric dipole consists of two point charges equal magnitude and opposite in sign (i.e., q and q ). a) Draw a diagram of a simple electric dipole and sketch in its electric field lines. b) Give the general formula of the electric field of the simple dipole in polar coordinates where the radius r is measured from the midpoint between the two charges (which is the conventional origin) and the polar angle θ is measured from the positive side of the axis through the two charges. Give the formula in terms of vector r , r (the magnitude of vector r ), θ , vectora (the vector from the origin to the positive charge q ), vectora (the vector from the origin to the positive charge q ), and a

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
