Worked Solution & Example Answer:Two small objects, P and Q, are each given an electric charge - Edexcel - GCSE Physics - Question 2 - 2021 - Paper 1
Step 1
Use information from Figure 3 to give two differences between the charge on P and the charge on Q.
Answer
- The electric field lines around object P are more dense compared to those around object Q, indicating that object P has a larger charge.
- The direction of the electric field lines from object P and object Q may differ, suggesting that one object is positively charged while the other is negatively charged.
Step 2
State the effect that the electric field of object P has on object Q.
Answer
The electric field of object P exerts a force on object Q, causing it to either attract or repel depending on the nature of the charges. If object P is positively charged and object Q is negatively charged, they will attract each other; if both are positively charged or both negatively charged, they will repel each other.
