Physics students, wanted to investigate the forces of attraction (F) between two parallel conductors carrying currents li and l2(also known as Ampere's Law)The students noticed that as the length of the parallelconductors (/) was increased the force of attraction betweenthe conductors (F) also increased. The data collected is in the|L= SAconductor 1average separation(d = 0.50m)table:conductor 2Length, / (m)Force, F (x 10-5 N)12= 5A1.009.001.2010.81.4012,51.6014.21.8016.2(iii) On the grid plot the force and length values fromthe table.(iv) Draw the line of best fit(v) Find the slope of the line of best fit.(c) Use the slope calculated and the Ampere's Lawequation to determine the experimental value ofthe magnetic force constant, k.

Solution: The plot of the length versus force is drawn below.
