Using the differential form of Gauss’s law ( ∇. D = ρ v ) derive in detail the integral form of
Gauss’s law? Obtain an expression for the capacitance of the coaxial cable shown in Figure 1?
(Note that for the given voltage V across the capacitor, charge +Q and –Q will accumulate
on the surfaces of the outer and inner conductors, respectively) Figure 1 Q3 A point charge 5 nC is located at (-3, 4, 0) while line y = 1, z = 1 carries uniform charge 2
(a) If V = 0 V at O(0, 0, 0), find V at A(5, 0, 1).
(b) If V = 100 V at B(1, 2, 1), find Vat C(-2, 5, 3).
(c) If V = - 5 V at O, find VBC. ALL THE BEST
