1. Two identical metal plates with small holes are aligned a distance L=5.8 cm apart. They have a potential difference of 115 Volts. An electron can enter through the hole in the negative plate and exit through the hole in the positive plate. If it enters with a velocity of 4620 km/s at the negative plate, with what velocity does it exit at the positive plate

2. A +67 ^oC charge is placed 39 cm from an identical +67 ^oC charge. If you assume the potential at infinity is zero, then what is the potential midway between the two charges? How much work is done to move a 0.60 ^oC charge from a point midway between the charges to a point 10 cm closer to either of the charges?

3. An evacuated tube uses an accelerating voltage of 44.0 kV to accelerate electrons to hit a copper plate and produce x rays. Non-relativistically, what would be the maximum speed of these electrons?
