Introduction Two massive charges +Q = +20e, and Q = -20e (where e is the fundamental electric charge, 1.6 × 10-19 C), orbit each other in a circle of radius s = 6 x 10-6 m, making a dipole. A comparatively small charge -q = -4e, with mass 0.0555556 kg is placed initially at rest far from the dipole a distance R = 50 m, as seen in the diagram below. During the ensuing motion of all the three charges, you can assume that the force on the dipole due to the small charge does not affect the motion of the dipole. You may also safely ignore the gravitational interaction of these particles. Use k = 9 × 109 m² for Coulomb's constant. + R -q (For all blanks below, enter a formula or a numeric answer. Responses are accepted with a ±1% tolerance.) Determining the charge's motion 3. Assuming the small charge starts from rest, determine the speed of the charge a short time 0.0277778 seconds later. 8.852-10-37 m/s 4. Predict how far the small charge will move during this time interval. -38 1.229-10 m
