Fig. 10.1 illustrates the apparatus used in an electrostatics experiment. The equipment comprises: iron nail, aluminium clamp and stand, cotton thread, plastic stirrup and polythene strip.
(a)[1]
Decide which pieces of equipment are electrical conductors and which are electrical insulators. Draw a line from every item to the appropriate box.
(b)[2]
State and explain how a negative charge can be produced on the polythene strip.
(c)[2]
Describe how the apparatus in Fig. 10.1 could be used to show that the polythene strip is negatively charged.
