Question

1.a) What type of motion does an electron initially moving at 1.5x10^6m/s parallel to the 2 V equipotential line in an ideal capacitor (as shown above) show? Explain, referring to the acceleration and similarity to a motion in a gravitational force.

b) When the electron reaches the 7 V equipotential line, what angle theta does its velocity vector make with the equipotential line? e=1.602x10^-19 C, me=9.11x10^-31 kg.

2.a) At what initial speed would one have to send a positron (a positively charged “antiparticle” of the electron, with the same mass and equal but opposite sign charge) perpendicular to the equipotential lines from the 2 V equipotential line (see top of the figure above) for it to have the same speed as the electron in question 1?

b) If another electron was initially moving toward lower electric potential from the 3V equipotential line, at what initial speed would it have to be released for it to have the same speed as the electron in question 1?
