10. An electron (charge -1.60 x 10-19 C and mass 9.11 x 10-31 kg) is initially at rest at the center of a uniformly charged ring of radius 3 mm and linear charge density ^ = -4.07 nC/m. The electron is nudged slightly and starts accelerating away from the ring along its central axis. Which of the following is closest to the electron's speed by the time it is very far from the ring? a) 5.0 x106 m/s d) 8.0 x 106 m/s c) 7.0 x 106 m/s b) 6.0 x 106 m/s e) 9.0 x 106 m/s
