Final answer:
The linear charge density of a thin rod with a charge of 2.20 nc and length of 1.20 m is 1.833 nc/m, calculated by dividing the total charge by the length of the rod.
Step-by-step explanation:
The student has asked to determine the linear charge density of a thin rod with a uniform charge q of 2.20 nc (nanocoulombs), distributed along a rod of length 1.20 m. The linear charge density (λ) is defined as the charge per unit length along a charged object.
To find the linear charge density of the rod, we use the formula:
λ = q / L
Substituting the given values:
λ = 2.20 nc / 1.20 m
λ = 1.833 nc/m
Therefore, the linear charge density of the rod is 1.833 nc/m.
