Dimension of the electric charge

In summary, the conversation discussed an experiment to determine the dimensions of electric charge in terms of m, kg, and sec. The answer provided was kg^(1/2)*m^(3/2)/sn, which can be found by considering epsilon zero to be dimensionless. It was also suggested to check out Max Born's theory of relativity for further understanding. The conversation concluded with a reminder not to resurrect old threads without good reason.

could someone told me an experiment that ı can find the dimensions of the electric charge in therms of m, kg, sec
the answer is kg^(1/2)*m^(3/2)/sn it can be found by assuming the epsilon zero is dimensionless
please say me an experiment that i can check it :confused: :confused:

If permittivity is dimensionless, then from Coulomb's law, q^2/r^2 has dimensions of force. That's all you need to prove it.

Check out Max born's Einsteins's theory of relativity. He uses the cgs. system. e=cm(gm cm)^.5/sec. But what is the square root of a gram centimeter?

Hello Brian, welcome to Physics Forums.
Are you aware this thread is over 7 years old?

Resurrecting old threads without good reason is frowned on.

There are a few different experiments that can be used to determine the dimensions of electric charge in terms of mass (kg), length (m), and time (s). One example is the Millikan oil drop experiment, which measures the charge of an electron by balancing the gravitational force on a charged oil droplet with the electric force created by an electric field. From this experiment, the dimensions of electric charge can be determined by analyzing the equations used to calculate the electric force and gravitational force, which involve mass, length, and time.

Another experiment that can be used is the Coulomb's law experiment, which measures the force between two charged objects. By analyzing the equations used to calculate this force, the dimensions of electric charge can also be determined.

Both of these experiments involve measuring forces and using equations that involve mass, length, and time, which allows for the determination of the dimensions of electric charge. Additionally, other experiments such as the Faraday cage experiment and the charge on a capacitor experiment can also be used to determine the dimensions of electric charge.
 

1. What is the electric charge?

The electric charge is a fundamental physical property of matter that determines how it will interact with other matter and electromagnetic fields. It is measured in units of coulombs (C).

2. How is electric charge measured?

Electric charge is measured using an instrument called an electroscope, which can detect the presence and magnitude of an electric charge. It can also be measured indirectly by observing the effects of electric charge on other objects or through mathematical equations.

3. What is the difference between positive and negative electric charge?

Positive electric charge is caused by an excess of protons in an atom, while negative electric charge is caused by an excess of electrons. These opposite charges attract each other, while like charges repel each other.

4. Can electric charge be created or destroyed?

No, electric charge is a conserved quantity, meaning it cannot be created or destroyed. It can be transferred from one object to another, but the total amount of charge in a closed system will always remain the same.

5. How does the dimension of electric charge affect its interactions?

The dimension of electric charge is a fundamental property that determines the strength of the electromagnetic force between charged particles. The greater the magnitude of the charge, the stronger the force of attraction or repulsion between particles will be.
