Apair of closely spaced parallel conducting plates, charged with equal and opposite electric charges, produces a uniform electric field in the region between them. in designing a cutting-edge device that will revolutionize the electronics industry, you set up such a pair of plates with a separation of 0.897 mm between them and charge them so that the direction of the electric field in their interior region is from plate a to plate b. your idea requires that electrons, when released from rest at one of the plates, reach the other plate at the speed of 1.29% of the speed of light. (the speed of light is c = 3.00 × 108 m/s.) at which plate should the electrons be released?
