Question

a. which line in the graph best represents the relationship between charge and force as described in coulombs law, and could explain why the effectiveness of many n95 masks decreases with use? select your choice
line a
line b
line c
line d

Explanation:

Coulomb's law states that the electrostatic force \(F\) between two point - charges is directly proportional to the product of the charges \(q_1\) and \(q_2\) (\(F = k\frac{q_1q_2}{r^2}\), when distance \(r\) is constant, \(F\propto q_1q_2\)). This is a linear relationship. Line C shows a linear relationship between the product of charges and force. The decrease in effectiveness of N95 masks with use is not related to the relationship shown in the graph. It is mainly due to factors like clogging of the filter material with particles and degradation of the electrostatic charge on the fibers over time.

Answer:

C. Line C
