Define electric field strength.
A uniform electric field is produced between two vertical metal plates shown in Fig. 1.1.
Fig. 1.1
On Fig. 1.1, draw lines to represent the electric field between the plates.
The metal plates are 50 mm apart. When the switch is closed, the plates are charged by a 200 V dc supply, as shown in Fig 1.2.

Calculate the electric field strength between the plates when the switch is closed.
State an appropriate unit for your answer.
A small polystyrene ball of charge –0.15 μC is suspended between the metal plates, as shown in Fig. 1.3.
