MCQ
Two identical positive charges are fixed on the $y$ -axis, at equal distances from the origin $O$. A particle with a negative charge starts on the $x$ -axis at a large distance from $O$, moves along the $+ x$ -axis, passes through $O$ and moves far away from $O$. Its acceleration $a$ is taken as positive in the positive $x$ -direction. The particle’s acceleration a is plotted against its $x$ -coordinate. Which of the following best represents the plot?
- A
- ✓
- C
- D
