F = qE = 1.6 x 10^-19 x 75 = 1.2 x 10^-17 N
acceleration = F/m = 1.318 x 10^13 m/s^2
time to reach the other plate =
S = .5 x a x t^2
3 x 10^-3 = .5 x 1.318 x 10^13 x t^2
t = 2.13 x 10^-8 s
velocity perpendicular to the plate = at = 1.318 x 10^13 x 2.13 x 10^-8
v = 2.8 x 10^5 m/s
total velocity = root (2.8 x 10^5^2 + 5.5 x 10^4 ^2)
= 2.8 x 10^6 m/s

As shown in the figure, an electron is fired with a speed of 3.59 × 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.24 m
As shown in the figure, an electron is fired with a speed of 3.59 × 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.24 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field so that...
