Question

If two objects are electrically attracted to each other, 4) A) one object must be negatively charged and the other object must be positively charged. B) both objects must be positively charged. C) both objects must be negatively charged. D) the objects could be electrically neutral. E) None of the above statements are absolutely true. Answer: D

Answer 1

Answer : The correct option is, (E) None of the above statements are absolutely true.

Explanation :

As we know that, electric charge is carried by the subatomic particles. That means, negative charge is carried by electrons and positive charge is carried by protons.

There are two types of electric charge.

Positive charge

Negative charge

The positive charge is created when the number of protons are more than the number of electrons.

The negative charge is created when the number of electrons are more than the number protons.

As we know that like charges repel each other and unlike charges attract each other.

When one object is positively charged and another is negatively charged then there is some force of attraction between them. Thus, two objects are electrically attracted to each other.

But electric for of attraction also exist between charged object and neutral object.

Hence, correct option is, (E) None of the above statements are absolutely true.

Answer 2

Answer:

option (a)

Explanation:

There are some properties of charge given as

(a) Charges are of two types: negative charge and positive charge.

(b) Like charges repel each other and unlike charges attract each other.

(c) charges are conserved in nature.

(d) charges are quarantined.

So, the two charges which are opposite in nature can only attract each other.

So, if there is one negative and one positive charge, they always attract each other.

The force of attraction or repulsion between the two charges is given by the Coulomb's law.
