(a)[1]
What does the term electric field mean?
(b(i))[2]
On Fig. 7.1, add lines to show the electric field between the plates.
(b(ii))[2]
Calculate the strength of the electric field between the plates.
(b(iii))[3]
Calculate the work done on the $\alpha$-particle by the electric field as it moves from AB to CD.
(b(iv))[1]
$\beta$-particle moves from AB to CD. Calculate the ratio $$\frac{\text{work done by the electric field on the }\alpha\text{-particle}}{\text{work done by the electric field on the }\beta\text{-particle}}.$$ Show your working.
