For the configuration shown in Figure P24.57, suppose that a = 5.00 cm, b = 20.0 cm, and c = 25.0 cm. Furthermore, suppose that the electric field at a point 10.0 cm from the center is measured to be 3.60 x 103 N/C radially inward while the electric field at a point 50.0 cm from the center is 2.00 x 102 N/C radially outward. From this information, find (a) the charge on the insulating sphere, (b) the net charge on the hollow conducting sphere, and (c) the charges on the inner and outer surfaces of the hollow conducting sphere.

Two conducting hollow spheres share a common center. The inner sphere has the radius a = 5.0 cm and charge +3.2x10-6 C. The outer sphere has the radius b = 32 cm and charge -4.0x10-6 C. What is the electric field (in N/C) at a point P, r = 20 cm from the center of the spheres?

An unknown charge sits on a conducting solid sphere of radius 9.5 cm. If the electric field 13 cm from the center of the sphere has magnitude 4.3 × 103 N/C and is directed radially inward, what is the net charge on the sphere?

For the configuration shown in the figure below, suppose a-5.00 cm, 620.0 cm, and c25.0 om, furthermore, suppose the electric field at a point 16.5 cm from the center is measured to be 3.05 x 10³ N/C radialty inward and the electric field at a point 50.0 cm from the center is of magnitude 161 N/C and points radially outward. From this information, find the following. (Include the sign of the charge in your answer.) (a) the charge on the insulating sphere Do the charges on the conducting shell affect the electric held at this point? C (b) the net charge on the hollow conducting sphere What is the total charge inside a sphere of radius 50 cm? C (6) the charge on the inner surface of the hollow conducting sphere (d) the charge on the outer surface of the hollow conducting sphere Need Help? Ref W

Figure (a) shows three plastic sheets that are large, parallel, and uniformly charged. Figure (b) gives the component of the net electric field along an x axis through the sheets. The scale of the vertical axis is set by Es = 5.4 × 105 N/C. What is the ratio of the charge density on sheet 3 to that on sheet 2?

Consider a closed triangular box resting within a horizontal electric field of magnitude E = 7.80×104 N/C as shown in the following figure. Calculate the electric flux through (a) the vertical rectangular surface (the 10 cm × 30 cm surface), (b) the slanted surface, and (c) the entire surface of the box. 10.0 cm 30.0 cm 60.0°
