Question

Ben Franklin used a hemp string to hold a kite flying in an electric storm. Charge accumulated on the hemp string. What would be a good choice for the units of the charge density on the string?

a. A/m
b. A/m²
c. C/m
d. C/m³

Answer 1

The correct units for the charge density on Benjamin Franklin's kite string would be coulombs per meter (C/m), as it represents the linear charge density along the string.

Step-by-step explanation:

The units of charge density on the string used by Benjamin Franklin when flying a kite in an electric storm would be coulombs per meter (C/m). This unit measures the amount of electric charge per unit length along the string. Option 'c. C/m' is the correct choice as it signifies a linear charge density, which is the most appropriate measure for charge distributed along a one-dimensional object, such as a string. Other units like coulombs per meter squared (C/m²) or coulombs per meter cubed (C/m³) would be used for surface or volume charge densities, respectively, which are not suitable for this case.
