r squared refers to the separation distance of the two charges in the system.
In respect to this, how do you calculate Coulombs?
Charge in Coulombs = Current in Amperes × Time in Seconds
If a current of 30 A flows for 50 s, then the electrical charge in the circuit is 1500 C.
Thereof, how do you find the radius in Coulombs law? If the electrostatic charge and force are known, then it’s possible to use Coulomb’s Law to find the distance between the objects. So, the distance between objects r is equal to the square root of the Coulomb constant ke times the charge of an object q1 times the charge of the other object q2 divided by the force F.
Considering this, how do you solve for K in Coulombs law?
The constant of proportionality k is called Coulomb’s constant. In SI units, the constant k has the value. k = 8.99 × 10 9 N ⋅ m 2 /C 2. The direction of the force is along the line joining the centers of the two objects.
What does the R variable represent in Coulombs law?
In Coulomb’s law, r2 refers to the square of the separation distance of the two charges in the described system.
