The population in a certain city has radial density function ρ(r) = 15(1 + r2)−1/2, where r is the distance from the city center in kilometers and ρ has units of thousands per square kilometer. How many people live in the ring between 10 and 30 km from the city center?
Calculate the mass of the straight wire from x = 0 to x = , where as
the density function is p(x) = tan (; x)

8.99 x 10⁹ Nm²/C², to compute the electric potential V (P) at the point P for the given charge density (in
units of 10-6 C/m.)
Calculate V (P) at P = (0, 0, 8) if the electric charge is distributed along the quarter circle of radius 4 centered at the
origin, lying in the first quadrant of the xy-plane with charge density 6 (x, y, z) = xy. Suppose that all distances are in
meters. Express the value of potential in kV, that is 1000 V.
(Give your answer to one decimal places.)
