(b)[2 marks]Explain why this force occurs.
Question 22
1 mark · Easy
Answer and check →Which action would NOT result in a force of attraction or repulsion between two objects?
- A.Bringing two positively charged rods close together
- B.Bringing a negatively charged balloon close to a wall
- C.Bringing an uncharged rod close to another uncharged rod

Question 23
2 marks · Easy
Answer and see the solution →A neutral metal sphere is suspended by a thread. A negatively charged rod is brought close to, but not touching, the sphere.
(a)[1 mark]Describe what happens to the sphere as the rod is moved closer.
(b)[1 mark]Explain, in terms of charges, why this occurs.
Question 24
2 marks · Easy
Answer and see the solution →A student has two rods: Rod A (positively charged) and Rod B (uncharged).
(a)[1 mark]Predict what happens if Rod A is brought near Rod B and state the type of force involved.
(b)[1 mark]Explain your answer.
Question 25

Question 28
4 marks · Normal
Answer and see the solution →A student hangs a thin strip of aluminium foil from a wooden support. The foil is initially uncharged. She brings a charged rod near it and observes the foil moving towards the rod.
(a)[1 mark]Describe what type of force acts between the charged rod and the uncharged foil.
(b)[2 marks]Explain, in terms of charge, how the uncharged foil is able to be attracted to the charged rod.
(c)[1 mark]State what happens if the foil and the rod become similarly charged and the rod is brought near again.
