Question

For a linear charge distribution, if the linear charge density is λ and a small element has length dl, what is the charge element dq?

पर्याय

• dq = λ dl

• dq = λ dS

• dq = λ/dl

• dq = λ dV

Answer 1

For a linear charge distribution, the charge element dq is related to the linear charge density λ and the infinitesimal length element dl by the relationship dq = λ dl. This comes directly from the definition λ = dq/dl.
