SUMMARY

The discussion centers on the analysis of a rod with a charge density defined as ##λ(x) = bx##, where ##b## is a constant. The dimension of ##b## is determined to be ##\frac{C}{m^2}##, indicating that it represents charge per unit area. Additionally, the total charge ##Q## of the rod is calculated using the integral ##Q = \int_0^L λ(x) \, dx##, resulting in the formula ##Q = \frac{bL^2}{2}## for a rod of length ##L##.

Homework Statement


there's a rod and charge density ##λ## is a function of ##x##, so simply ##λ(x)=bx## and b is a constant.Find the dimension of ##b##
and Find the total charge If the length of rod is L

Homework Equations


Dimension Analysis equataion

The Attempt at a Solution


[/B]I am thinking like rod is 1 dimensional object so the dimension of b will be ##\frac {C} {m^2}## and total charge of rod will be,
## Q=\int_0^L λ(x) \, dx## and from that ##Q=\frac {bL^2} {2}##

Is this true ?
