Worked Solution & Example Answer:Two charged rods are brought close together - OCR Gateway - GCSE Physics - Question 2 - 2021 - Paper 1
Step 1
C Opposite charges attract so the rods move towards each other.
Answer
When two charged rods are brought close together, we must consider the type of charges they possess. In this scenario, if both rods are positively charged (as indicated by the symbols '++'), they will repel each other according to the fundamental principle that like charges repel. However, if one rod were negatively charged, the two rods would exhibit an attractive force due to opposite charges. Since the question does not specify that one of the rods is negatively charged, the correct interpretation within the context provided here indicates that both rods being positively charged would move away from each other, affirming choice D as the statement that correctly explains the behavior of the rods.
