PHY 232 Exam 1 2026 Questions and
Answers
Oppositely charged parallel plates are separated by 5.08 mm. A potential difference
of 600 V exists between the plates. What is the magnitude of the electric field
between the plates? What is the magnitude of the the force of the electron between
the plates?(c) How much work must be done on the electron to move it to the
negative plate if it is initially positioned 2.80 mm from the positive plate? - Correct
answer-E= V/r, F= q(e)*E,W=|F*d|cos(theta),
