Question

Which of the following statement(s) about electrical charges are correct?

A. Point charges of the same charge only attract.
B. Charged and neutral extended objects can attract.
C. Charged and neutral extended objects do not interact.
D. Point charges of the same charge only repel.
E. Extended objects of opposite charge can only attract.
F. Point charges of opposite charge only attract.
G. Point charges of opposite charge only repel.
H. Extended objects of the same charge can both repel and attract.
I. Extended objects of the same charge can only attract.
J. Extended objects of the same charge can only repel.
K. Extended objects of opposite charge can both repel and attract.

Answer 1

In the context of electrical charges, like charges repel each other while opposite charges attract. Charged objects can also induce polarization in neutral objects, causing attraction. The correct statements about charge interaction are: D, B, E, F, and J.

Step-by-step explanation:

The question is about the behavior of electrical charges and how they interact with one another. In general, charges can be either positive or negative, and their interactions are governed by some basic principles:

• Like charges repel each other.
• Opposite charges attract each other.
• Charged objects can induce polarization in neutral objects, leading to attraction.

Given these principles, here are the correct statements from the options provided:

• Point charges of the same charge repel one another (D).
• Charged and neutral extended objects can attract due to polarization effects (B).
• Extended objects of opposite charge always attract each other (E).
• Point charges of opposite charge attract each other (F).
• Extended objects of the same charge repel each other (J).

Answer 2

The true statements are;

F, D, E, J

Step-by-step explanation:

F and D are true because they agree with our knowledge of electrostatic interaction. Like charges repel while unlike charges attract. Statements B and C are not in line with the principles of electrostatics because neutral objects do not interact with charged bodies in an electric field.

E and J are true for the same reasons outlined above. Remember that like charges always repel each other and unlike charges always attract each other.
