Passage VII
Identical spheres, X and Y, had electrical charges Qx and QY, respectively. Throughout each of 13 trials, the spheres remained fastened to the horizontal floor of a vessel a distance d apart, with X due east of Y (see Figure 1).
The vessel was filled with a medium having a dielectric constant, K. (K reflects a medium's ability to modify the electrical force between charges.) X exerted an electrical force of magnitude FY on Y, and Y exerted an electrical force of magnitude Fx on X. Each force was directed either east or west.
Table 1 lists K for 4 media. Table 2 lists Qx, QY, d, the medium, Fx, and FY for each trial.
37. Suppose that Sphere X had become unfastened from the floor of the vessel during Trials 1 and 7. During which of these trials would Sphere X more likely have undergone the lesser amount of acceleration?
Your Answer is
Correct Answer is B
Explanation
Lesser amount of acceleration is small, indicating that the force FX received is small. Looking at table 2, FX in trails 1 & 7, it is obvious that 0.23 in trial 1 is smaller
