Question

Positive charge Q is distributed uniformly along a rod of length L that lies along the z-axis from = L to 2 = 2L. How much charge is contained within a segment of the rod of length da? Express your answer in terms of the variables Q, L, and d

Answer 1

The charge density is given by λ = Q/L, where Q is the total charge on the rod and L is the length of the rod. The charge contained within a segment of the rod of length da can be determined by integrating the charge density along that segment using the formula dq = (Q/L) * da.

Step-by-step explanation:

The charge contained within a segment of the rod of length da can be determined by integrating the charge density along that segment. The charge density is given by λ = Q/L, where Q is the total charge on the rod and L is the length of the rod. The charge contained within a segment of length da is then given by dq = λ * da = (Q/L) * da.
