Compute all parts of following problem given below:
Problem: The value of the proportionality constant in the Biot-Savart Law depends upon experimental results and upon the units being used.
Part A: What is the value of this constant in the SI system?
Part B: What is the ratio of this constant to the constant in Coulomb's Law (in the same units)?
Part C: How is the answer in (b) related to the speed of light in a vacuum?
I need help to find the ratio of this constant to the constant in Coulomb's Law.
