A student measured the Coulomb force between a positive charge (+400 µC) and a negative charge (-600 µC) for different distances between them. The student plotted the force (expressed in newtons) as a function of the inverse distance squared (in inverse squared meters) with the goal of extracting the Coulomb factor, k. The resulting graph, including the trendline, is shown in Figure 2a. Based on this graph, the value of k is: 8.98 x 109 N m²/c2 - 8.88 x 109 N m²/c2 - 8.78 x 109 N m²/c2 8.68 x 109 N m²/c2 8.68 x 108 N m2c2 8.99 x 108 N m2c2 8.38 x 109 N m21c2 9.08 x 109 N m²/c2

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
