You awake one morning and, as sometimes happens, you find that you have been transported to an alternate universe where the laws of physics are all the same, but the universal constants are different. You measure that the speed of light is
1.95×108 ??1.95×108 ms
1.95×108 ??1.95×108 ms. You then determine that in the middle of a flat coil with 5000 loops of radius 5.00 cm and a current of 5.60 A running through it, there is a magnetic field of 0.1056 T.
What is the permittivity of free space in this universe?
