Question
Positively charged particles start in the center of a uniform electric field (created by the charged gray plates; the field is shown, but fringe effects are not). When you push "play," four particles leave the parallel plates and head toward the detector. The graph simply plots the signal at the detector: showing a spike every time a particle hits the detector (position is given in centimeters and time is given in microseconds). This is a time-of-flight mass spectrometer and is used to detect what types of charged particles are in an atomic beam. Restart.Given that the electric field is uniform and the voltage at the left plate is 2000 V and at the right plate is 0 V, explain how you know that the voltage in the middle of the plates (where the particles are) is 1000 V.
How much potential energy does each charged particle have if its charge is 1.6 x 10-19 C? (Each need one electron to be neutral again.)
Explanation / Answer
Using U = qV , we find that the system consisting of one charged particle has a potential energy of U = (1.6
