ANSWER:
Step 1 of 2:-
a)
Here, we have to calculate the speed of electrons.
The magnetic field is perpendicular to the direction of motion of electrons.
The magnetic field strength is,
.
The voltage difference between the electrodes is,
.
We know that,
Because, the net force has to be zero for the electrons to continue in the straight path.
So, the speed of the electrons will be 1.09 m/s.
