Question 974: Electrostats & Capacitance

Question

An electric charge does not have which of the following properties?

Accepted Answer

The correct option that represents a property not associated with an electric charge is Option D: Circular line of force.
Let's examine each option closely to understand why:
Option A: Total charge conservation
- This principle states that the total charge in an isolated system remains constant. This is a fundamental property of electric charge, governed by the law of conservation of charge. It means that in any process, the sum of all the electric charges before the process equals the sum of all the electric charges after the process, indicating that electric charge cannot be created or destroyed, only transferred from one body to another.
Option B: Quantisation of charge
- The quantization of charge means that the charge on an object is always an integer multiple of the elementary charge (e), where $e = 1.6 \times 10^{-19} $ Coulombs. No matter how small, a charge canÃ¢ÂÂt be a fraction of this elementary charge, thus demonstrating that charge is quantized.
Option C: Two types of charge
- There are indeed two types of electric charges: positive and negative. This dichotomy is foundational to the structure of electromagnetism, where like charges repel each other and opposite charges attract each other. This property is fundamental to the behavior of charged particles and underlies practically all electric phenomena.
Option D: Circular line of force
- Electric lines of force or electric field lines emanating from a charged particle are radial and straight, originating from positive charges and ending at negative charges. They are not circular in nature under normal circumstances. The concept of circular lines of force is more appropriately linked to magnetic fields around a current-carrying conductor or the magnetic field of a bar magnet, not to electric charges directly. Therefore, Option D is a property that does not belong to electric charges.
