Difference between the cathode and the anode in Volts

Reference no: EM13652800

An investigation is performed using a apparatus. Electrons are accelerated from rest from the cathode by an electric potential difference. The cathode and anode are 2.00 x 10 ^-2 cm apart. The electrons reach a speed of 2.10 x 10^7 m/s as they pass through the hole in the anode.

Electrons then pass undeflected through a region in which there is both an electric and a magnetic field. The electron field is produced between two plates ( plate 1 and plate 2) which are 3.00cm apart. Plate 1 is postively charged and plate 2 is negatively charged. The electric potential difference between the plates is 12.0 V. Two current- carrying coils produce a magnetic field that is perendicular to the electric field.

1) What is the electric potential difference between the cathode and the anode in Volts?
2) The electric field between plate 1 and plate 2 is

a) 4.00 x 10^2 toward plate 1
b) 4.00 x 10^2 toward plate 2
c) 4.00 x 10^4 toward plate 1
d) 4.00 x 10^4 toward plate 2
