Explanation:
When a point charge is brought into an electric field, the electric field at a nearby point can be affected by the charge. The behavior of the electric field depends on the properties of the charge being introduced.
Positive charge:
- When a positive charge is brought into an electric field, it will create its own electric field around it.
- Since like charges repel each other, the electric field of the positive charge will oppose the original electric field.
- This results in an increase in the electric field at the nearby point.
Negative charge:
- When a negative charge is brought into an electric field, it will also create its own electric field around it.
- Unlike charges attract each other, so the electric field of the negative charge will enhance the original electric field.
- This results in a decrease in the electric field at the nearby point.
Summary:
Based on the above explanations, we can conclude that:
- The electric field at a nearby point may increase if the charge being brought is positive (Option C).
- The electric field at a nearby point may decrease if the charge being brought is negative (Option D).
However, it is important to note that the behavior of the electric field also depends on the distance between the point charge and the nearby point, as well as the magnitudes of the charges involved. The above explanations provide a general understanding of how the electric field can be influenced by the introduction of a point charge.
