In SI, the unit for the linear density is the coulomb per meter C/m. In addition to the main SI unit for the linear charge density (C/m), decimal multiples C/cm are used. In the alternative centimeter-gram-second system of units (CGSM), abC/m and abC/cm are used. 1 abcoulomb is equal to 10 coulombs.
The linear charge density on the inner conductor is -80 nC/m and the linear charge density on the outer conductor is -10 nC/m. The inner and outer cylindrical surfaces are respectively denoted by A, B, C, and D, as shown. (ε 0 = 8.85 × 10-12 C2/N · m2) What is the magnitude of the electric field at a point that is 61 mm from the axis?
The formula of linear charge density is λ=q/l, such that q is the charge and l is the length of the body over which the charge is distributed. 2.
