Enter your 4 digit number _ _ _ _ , we'll call these numbers a,b,c,d		1234
Length of the deflecting plates is 1.ab E-1 m		l=1.12 E-1 m
Potential difference between cathode and anode of the electon gun is 1.cd E+3 V		V=1.34 kV
The electric field strength between the deflecting plates is 1.bc E+3 N/C		e= 1.23 kN/C

An electron gun in a cathode ray tube shoots a stream of electrons between two deflecting plates of length l (given above). The electrons are accelerated by an electrical potential between the anode and cathode of the electron gun (voltage given above). The electron beam is deflected by the electric field (strength given above) generated between the two deflection plates.

If the deflecting plates are separated by a distance of 3.00 mm, what is the potential difference between the deflecting plates?
What is the speed of the electrons leaving the gun?
How long does it take for the electrons to pass through the distance l ?
What angle u does the beam leave the deflecting plates?
