- An evacuated tube uses an accelerating voltage of 55 kV to accelerate electrons to hit a copper plate and produce X-rays. Non-relativistically, what would be the maximum speed of these electrons before hitting the copper plate? Hint Maximum speed of the electrons is m/s. (Use the "E" notation to enter your answer. For example, to enter 3.14 x 10¹2, type in "3.14E12".)
