When an ebonite rod is rubbed with the skin of a cat, the ebonite rod becomes negatively charged (option A). This phenomenon occurs due to the transfer of electrons. Ebonite, being a material that has a strong affinity for electrons, attracts and gains electrons from the cat’s skin during the rubbing process. As a result, the ebonite rod accumulates an excess of negatively charged electrons, which leads to it becoming negatively charged. The cat’s skin, having lost some of its electrons, becomes positively charged in turn. This transfer of electrons is a classic example of triboelectric charging, where contact and friction between two different materials result in one material gaining electrons and the other losing them. Therefore, the ebonite rod acquires a negative charge after rubbing with the cat’s skin.
Similar charges have repulsion (option C). This fundamental principle of electrostatics states that like charges repel each other. For instance, if two positively charged objects or two negatively charged objects are brought close to each other, they will experience a force that pushes them apart. TRead more
Similar charges have repulsion (option C). This fundamental principle of electrostatics states that like charges repel each other. For instance, if two positively charged objects or two negatively charged objects are brought close to each other, they will experience a force that pushes them apart. This is because similar charges create an electric field that exerts a force on other similar charges, causing them to move away from each other. This repulsive force is described by Coulomb’s Law, which quantifies the magnitude of the force based on the charges’ magnitudes and the distance between them. Attraction (option A) occurs between opposite charges, such as positive and negative. Adhesion (option B) and cohesion (option D) refer to forces that cause molecules to stick together, but are not related to the behavior of electrostatic charges. Therefore, similar charges always exhibit repulsion.
If the distance between two electric charges is halved, the value of the electric force between them will become quadruple (option C). This outcome is based on the principle that the electric force between two charges depends on the distance separating them. When the distance between the charges isRead more
If the distance between two electric charges is halved, the value of the electric force between them will become quadruple (option C). This outcome is based on the principle that the electric force between two charges depends on the distance separating them. When the distance between the charges is reduced by half, the electric force does not merely double; instead, it increases by a factor of four. This is because the relationship between the distance and the force is such that reducing the distance by a certain factor results in the force increasing by the square of that factor. Therefore, when the distance is halved, the force becomes four times stronger, illustrating how sensitive the electric force is to changes in distance.

The force between two electric charges is related to Coulomb’s law (option B). Coulomb’s law is a fundamental principle in physics that explains the behavior of electrostatic forces between charged particles. It describes how the magnitude of the force between two point charges depends on the amount of charge on each object and the distance separating them. The law highlights that the electric force increases with larger charges and decreases with greater distances. This principle is essential for understanding various electrostatic phenomena, such as the attraction or repulsion between objects and the behavior of electric fields. Coulomb’s law differs from Ampere’s law (option A), which deals with magnetic fields generated by electric currents; Faraday’s law (option C), which relates to electromagnetic induction; and Ohm’s law (option D), which describes the relationship between voltage, current, and resistance in an electrical circuit.
The entire charge of a charged conductor remains on its outer surface (option B). This phenomenon occurs because of the repulsive forces between like charges.

The entire charge of a charged conductor remains on its outer surface (option B). This phenomenon occurs because of the repulsive forces between like charges. When a conductor is charged, the charges redistribute themselves in such a way that they are as far apart as possible to minimize repulsive forces. This results in the charges moving to the outer surface of the conductor, creating an equilibrium state. Inside a conductor, the electric field is zero, so there is no force driving the charges to stay on the inner surface. This principle is fundamental to electrostatics and explains why the charges on a conductor reside entirely on the outer surface. Unlike insulators, where charges can remain stationary, conductors allow for the free movement of charges to achieve this state. Thus, the entire charge of a charged conductor resides on its outer surface.
