Units of P1 and P2 in Coulomb's Law

In summary, the units of P1 and P2 in Coulomb's Law are typically given in Coulombs (C), and their values can be calculated using the equation Q = P1 * P2 / (4πε<sub>0</sub>r<sup>2</sup>). P1 and P2 must have the same units in order for the equation to be valid, and they are inversely proportional in Coulomb's Law. These values represent the magnitudes of the electric charges and play a crucial role in determining the strength and direction of the electric force between two charged particles.

- What are the units of P1 and P2 in Coulomb's law for magnetic poles? (picture attached).
- What is the accurate name of 'P' : magnetic pole strength? Magnetic pole intensity?

PS: Sorry if my questions are too basic for this forum- I am not a Physicist.

1. What are the units of P1 and P2 in Coulomb's Law?

The units of P1 and P2 in Coulomb's Law are typically given in Coulombs (C), which is the unit of electric charge.

2. How do I calculate the value of P1 and P2 in Coulomb's Law?

The value of P1 and P2 can be calculated using the equation Q = P1 * P2 / (4πε0r2), where Q is the electric charge, r is the distance between the two charges, and ε0 is the permittivity of free space.

3. Can P1 and P2 have different units in Coulomb's Law?

No, P1 and P2 must have the same units in Coulomb's Law in order for the equation to be valid. This ensures that the values being compared are of the same type of physical quantity.

4. How are P1 and P2 related in Coulomb's Law?

P1 and P2 are inversely proportional in Coulomb's Law, meaning that as one value increases, the other value decreases. This relationship is expressed in the equation Q = P1 * P2 / (4πε0r2).

5. What is the significance of P1 and P2 in Coulomb's Law?

P1 and P2 represent the magnitudes of the electric charges in Coulomb's Law. These values are important in determining the strength and direction of the electric force between two charged particles.
