3) Find the value of the permeability of free space,0.Compare your experimental result with the accepted value.

Slope = m value found from graph = 7.1625

= (m)(2d) / L = (7.1625)(2(0.0087))/(0.27)= 1.45011

Accepted value of 0 is= ?

Error% = Experimental theoretical/ theoretical x 100= ?

5) Using your experimental value of0, and the accepted value of the permittivity of free space,0, compute the speed of light in a vacuum. How does this compare with the accepted value?
