A point positive charge is brought near an isolated conducting sphere (Fig. 1.2). The electric field is best given by which figure?
Understand the Problem
The question is asking which figure correctly depicts the electric field around a positive charge near an isolated conducting sphere. The user needs to select the correct figure from the given options.
Answer
Figure 1
The figure representing the correct electric field is figure 1.
Answer for screen readers
The figure representing the correct electric field is figure 1.
More Information
When a positive charge is brought near a conductor, the electric field lines emanate from the charge and induce an opposite charge on the nearest side of the sphere, while similar charges repel on the far side.
Tips
A common mistake is not considering the induction effect that causes charges to redistribute on the conducting sphere.
