Problem

During an experiment, a student sends electromagnetic pulses through a long evacuated tube and finds that the pulses cover a distance of

120\,\text{m}

4.007 \times 10^{-7}\,\text{s}

. a. (i) Calculate the experimental value of the speed of the pulses. b. (ii) Taking

\varepsilon_0 = 8.854 \times 10^{-12}\,\text{C}^2\,\text{N}^{-1}\,\text{m}^{-2}

, use the value obtained in (i) to compute an experimental value of the vacuum permeability

\mu_0

. c. (iii) The accepted value of

\mu_0

4\pi \times 10^{-7}\,\text{N\,A}^{-2}

. Determine the percentage deviation of the student’s value from the accepted value. d. (iv) List any two possible experimental factors that could account for the deviation obtained in part (iii).
