adajett asked:


an electron in a computer monitor enters midway between two parallel oppositely charged plates. The initial speed of the elctron is 6.15 X 10^7 m/s and its vertical deflection is 4.70 mm
a) what is the magnitude of the elctric field between the plates
b) determine the magnitude of the surface charge density on the plates in C/m^2
can u please work me thru this or at least explain wat u did.
