What is the significance of the proportionality constant in physics and how does it affect the relationship between different physical quantities?
The proportionality constant in physics is important because it defines the relationship between different physical quantities in an equation. It determines how one quantity changes in relation to another. For example, in Newton's second law of motion, the proportionality constant relates force to acceleration. Changing the value of the proportionality constant can alter the strength of the relationship between the quantities being studied.
What is the unit of coulombs force?
The unit of force in the Coulomb's law equation is the Newton (N).
What is the spring constant of a spring that stretches 12 cm when an object weighing 24 N is hung from it?
The spring constant is 200 N/m. This is found by using Hooke's Law, which states that the force exerted by a spring is directly proportional to its extension, with the constant of proportionality being the spring constant.
What is the relation between k and permittivity of free space?
The permittivity of free space, denoted by ε₀, is a physical constant that represents the ability of a material to store electrical energy in an electric field. It is related to the Coulomb's constant k (also known as electrostatic constant) by the equation k = 1 / (4πε₀), where k is a proportionality constant in Coulomb's law.
What is G in physics and what is the value of G?
In physics, G usually refers to the gravitational constant, which is a fundamental constant that appears in the law of universal gravitation equation. The value of the gravitational constant is approximately 6.674 × 10^-11 m^3 kg^-1 s^-2.
What does the proportionality constant k in coulombs law is huge in ordinary units whereas the proportionality constant g in newtons law of gravition is tiny mean?
It means that the force of electrical attraction (or repulsion) between two particles with units charges will be greater than the gravitational attraction between two particles with unit mass which are the same distance apart.
What are the limitations coulombs law?

What are the units of the Coulomb constant k which appears in Coulomb's law?
newtons * meters squared / coulombs squared
What is ohms law constant of proportionality?
1 volt applied across one ohms Will conduct one Ampere
Is coulombs law a universal law?
No
What is the unit of coulombs force?
The unit of force in the Coulomb's law equation is the Newton (N).
How can the rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
How is coulombs law different from newton law?
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
Why pressure is constant in Charles law?
In Charles's Law, pressure is assumed to be constant because the law specifically focuses on the relationship between volume and temperature of an ideal gas when pressure is held constant. This allows for a direct proportionality between volume and temperature, showing that as temperature increases, the volume of a gas will also increase if pressure is held constant.
What equation is used for Kepler's 3rd law?
It is p2 = ka3where p is the orbital period, a is the semi-major axis of the orbit and k is a constant of proportionality.
What is the name of conductor which obeys ohm's law?
Everything obeys Ohm's law - antennas, cables, transformers, integrated circuits, etc.AnswerIt is not true that 'everything' obeys Ohm's Law. For a device to obey Ohm's Law, the ratio of voltage to current MUST remain constant for variations in voltage. This is why Ohm's Law is a law of constant proportionality.
