[1]

(b)

Write an equation for the magnetic force acting on a charged particle moving in a magnetic field.

[1]

(c)

the path taken by the electron in the magnetic field and the cause of this motion.

[2]

(d)

the speed of an electron accelerated from rest through a potential difference of 4.0 kV.
