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, leticia sets up such a pair of plates separated by a distance 0.879 mm, then charges them so that the direction of the electric field in their interior region points from plate a to plate b. her idea requires that electrons, when released from rest at one of the plates, reach the other plate at the speed of 1.97% of the speed of light. the speed of light is c = 3.00 x 10^8 m/s.
1. at which plate should the electrons be released?
o a
o b
o either
o cannot be determined
