Mysteries of Electrostatics Revealed: Unveiling the Truth behind Attraction Between Positively Charged and Neutral Objects

Yes, a positively charged object can attract an uncharged object. Positively charged objects exert electrical forces on neutral objects, causing them to be attracted to each other.

Complete answer

Yes, a positively charged object can attract an uncharged object. When an object becomes positively charged, it has an excess of protons compared to electrons. These positively charged protons create an electric field around the object, which can exert a force on nearby neutral objects.

According to Coulomb’s law, the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. So, even though an uncharged object has no net charge, it still contains both positive and negative charges. Thus, the positively charged object can attract the uncharged object by exerting a force on the negative charges within it.

To further delve into the topic, here are some interesting facts:

  1. Atoms, composed of a positively charged nucleus (protons) surrounded by negatively charged electrons, are the building blocks of matter. When electrons are transferred between objects, they can become charged.

  2. In nature, positive and negative charges attract each other. This is due to the fundamental principle in physics known as the Law of Electric Charges, which states that opposite charges attract while similar charges repel.

  3. The concept of electrical attraction is vital not only in understanding static electricity but also in various fields such as electronics, electromagnetism, and even biology (electric charges play a role in nerve impulses and muscle contractions).

  4. The ability of positively charged objects to attract uncharged objects can be observed in everyday life. For example, when you rub a balloon on your clothes, it becomes positively charged and can attract uncharged lightweight objects like small pieces of paper or hair.

Now, to add a touch of inspiration to the topic, here is a well-known quote by Albert Einstein:

“Nature shows us only the tail of the lion. But there is no doubt in my mind that the lion belongs with it even if he cannot reveal himself to the eye all at once because of his huge dimension.”

Answer in the video

In the video, it is explained that a plastic comb can attract paper due to the accumulation of static electricity. When the plastic comb rubs against dry hair, it gains an electric charge, making it electrically charged. Plastic is not a good conductor, so the charges build up in the comb, allowing it to exert a force on the pieces of paper and attract them. On the contrary, a metallic comb, being a good conductor, does not accumulate charges and therefore cannot attract paper like a plastic comb.

Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

Since "neutral" objects are made out of many positive and negative charges in equal measure, some of which can move, the presence of an electric field from a charged object will move these charges, and result in a region of opposite (to the object creating the field) charge where the neutral object is nearest to the charged object, and this will indeed result in an attraction between the formerly neutral object and the charged object.

If we bring it near an uncharged sphere, the sphere forms negative charge near the glass rod, and positive charged on the end away from glass rod. Since there is positive charge in rod, and negative charge in sphere, they attract

The interaction between two like-charged objects is repulsive. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

Any charged object can exert this force upon other objects – both charged and uncharged objects.

Yes we can. Actually a charged object always attracts an object which is opposite in charge. So a charged object tries to attract an object by imparting negative charges to one side of the uncharged object and that process of imparting negative charge is called induction.

A charged object attracts an uncharged object by producing opposite charge in the nearer end of the uncharged object by the process of: (a) electric potential (b) electric induction (c) friction (d) electromagnetic induction

The answer is YES. Charged particles indeed attract uncharged ones. This is due to the phenomenon of “Charging by Induction”. When a charged body (say negatively charged) is brought near an uncharged one, it induces an opposite charge (positive) on it and hence attracts it towards itself.

The charged objects attract uncharged objects by separating the charges on the uncharged object, that is the the charges of opposite nature to that of the charges on the charged object come closer. That is, the charged object induces opposite charges on the nearer surface of the uncharged object.

It is found that a charged object, whether positive or negative, may attract uncharged objects.

The answer is YES. Charged particles indeed attract uncharged ones. Hence, the ends of the two bodies develop opposite charges and mutual attraction occurs.
