What is the dimension of linear charge density?
A. [I T L-1]
B. [I T-1 L]

D. [I-1 T-1 L]
Answer:A
What is the dimension of linear charge density?
A. [I T L-1] B. [I T-1 L] C. [I T L] D. [I-1 T-1 L]
Explanation: Linear charge density λ=\(\frac {Amount \, of\, charge}{Total \, length}\). The dimension of electric charge = [I T] and the dimension of length is [L]. Hence the dimension of linear-charge-density = [I T L-1]. In the case of surface charge density, the dimension is [I T L-2] because it means charge stored on the unit surface area.
