Answer:

Explanation:
The force acting on the electron due to the magnetic field is

where
is the charge of the electron
is its speed
is the intensity of the magnetic field
is the angle between the direction of the field and the velocity of the electron
Substituting all the numbers into the equation, we find

One
d = 400 m
t = 20 s
speed = ?
speed = 400 / 20
speed = 20 meters/second
Two
d = 50 meters
t = 10 seconds
speed = 50 meters / 10 seconds
speed = 5 meters / second
