Fig. 7.1 depicts two charged metal plates, with X marking the midpoint of the region between them.
(a(i))[2]
On Fig. 7.1, sketch at least four field lines to show both the pattern and the direction of the electric field between the two charged plates.
(a(ii))[1]
Describe what happens to a negatively charged particle placed at X.
(b(i))[2]
Calculate the charge that moves from the cloud to the ground.
(b(ii))[2]
Calculate the potential difference between the base of the cloud and the ground.
