Academics

Two 2.5cm -diameter disks spaced 2.0 mm apart form a parallel-plate capacitor. The electric field between the disks is 4.1×105 V/m.

A) What is the voltage across the capacitor? Which I found to be 820 V

B) How much charge is on each disk? (Answer in Coulombs)

C) An electron is launched from the negative plate. It strikes the positive plate at a speed of 2.4×107 m/s. What was the electron's speed as it left the negative plate? (Answer in m/s)
