Weve been working as a group on campus now for a few hours and we're lost on these 3. Our teacher did a horrible job explaining this material and the book doesn't do any better of one.
A long, non-conducting, solid cylinder of radius 4.7 cm has a uniform volume charge density ρ = 2.1 µC/m^3.
a) What is the magnitude of the electric field at a radial distance of 6.5 cm from the axis of the cylinder?
1Your answer is incorrect. N/C
b) What is the magnitude of the electric field at a radial distance of 2.8 cm from the axis of the cylinder?
2Your answer is incorrect. N/C
Particle A proton with speed v = 3.00 multiplied by 105 m/s orbits just outside a charged sphere of radius r = 1.04 cm. What is the charge on the sphere?
1Your answer is incorrect. C
Concentric Spheres Two charged concentric spheres have radii of 9.5 and 14.7 cm. The charge on the inner sphere is 3.98 multiplied by 10-8 C and that on the outer sphere is 2.00 multiplied by 10-8 C.
(a) Find the electric field at r = 11.7 cm.
1Your answer is incorrect. N/C
(b) Find the electric field at r = 20.4 cm.
2Your answer is incorrect. N/C
Section 24.6 Application of Gauss' Law to Symmetric Charge Distributions
Surface of Cube At each point on the surface of the cube shown in Fig. 24-25, the electric field is in the positive direction of z. The length of each edge of the cube is 3.2 m. On the top surface of the cube, Evec = (-34 N/C)k, and on the bottom face of the cube Evec = (+19 N/C)k . Determine the net charge contained within the cube.
