How can one effectively introduce a research question in a paper, with an example for illustration?

Then, clearly state the research question that you aim to answer in your study. For example, in a paper about the impact of social media on mental health, the research question could be: "How does excessive use of social media contribute to feelings of anxiety and depression among young adults?"
