Part B: The effect of distance on the force of electrostatics A student performed an experiment that verified Coulomb's Law of Electrostatics by measuring the repulsion between 2 charged spheres, A and B, as a function of the separation of the spheres. The spheres were identical in size and mass. The measurements are shown in the table below. Table 1: The Electrostatic force as a function of the separation of the pith balls. Separation, r, (m) Electrostatic Force, Fa, (N) 0.10 0.790 0.13 0.480 0.20 0.200 0.40 0.050 0.60 0.022 (based on "Written Response Example", Physics 30 Exam Bulletin, January 2000, Alberta Learning) Using graphical analysis techniques confirm that these results support Coulomb's Law. Be sure to describe Coulomb's law and the expected graphical relationship Using the data find a meaningful Mathematical relationship between Force and Separation and discuss the meaning of the slope * Assuming k = 8.99 x10' Nm C and q, =3.00 x 10* C, find the magnitude of q 1.Format Trendline Trendline Options Trendline Options O Exponential Linear O Logarithmic O Polynomial Order 2 T O Power Moving Period 2 Average Trendline Name O Automatic Linear (Force F (N) O Custom Forecast Forward 0.0 period: Backward 0.0 period: Set Intercept 0.0 v Display Equation on chart Display R-squared value on chart
