Question

(a) The figure below shows a thin plastic rod of length L and uniform positive charge density of ?. Find an expression of the electric potential at point P in terms of ?, a, b and L, by integration formula. (Hint: ? dx/?(x²+a²) = ln(x + ?(x²+a²)) + C) (c) A face consists of 6 items as shown in the following figure. A thin rod of charge +20 nC/m forms a circle of radius 1.5r. A thin circular arc of charge + 10 nC and radius r. Two point charges of charge -2 nC each. Two linear thin rod of charge -4 nC each. Given a = 0.5 cm, b = 2.5 cm, c = 2 cm, d = 1 cm, L = 2 cm, and r = 3.2 cm. Using the result in part (a), determine the net electric potential at the center, P.
