4. (15 points) Two electrodes form a parallel plate capacitor. The plates each have a radius of 3.0 cm and the separation distance between them is 0.15 mm. One plate carries a charge of 50 nC, and the other carries a charge of -50 nC. If an electron is released from rest midway between the plates, what will be its speed when it hits the positive plate? 50×10-⁹ M = 1.76×10²'5 A) 5.3 x 10¹3 m/s B) 6.8 x 107 m/s C) 7.3 x 106 m/s D) 3.5 x 10¹7 m/s E) 2.0 × 106 m/s Answer: B 1998178.813 C
