A sphere of radius 5.00 cm c m carries charge 3.00 nC n C . Calculate the electric-field magnitude at a distance 4.00 cm c m from the center of the sphere and at a distance 6.00 cm c m from the center of the sphere if the sphere is a solid insulator with the charge spread uniformly throughout its volume.

- 8632.1N/C

- 17483.17N/C

Explanation:

Inside electric field magnitude is different of the outside electric field.

- Inside the sphere we have that the electric field is given by:

Where Q is the charge of the sphere, R is its radius and e0 is the dielectric permittivity of vacuum.

By replacing (r=5.00cm=5.00*10^{-3}m, e0=8.85*10^{-12}C^2/Nm^2) we get:

- Outside the sphere we have the formula:

hope this helps!!

truck y has a greater velocity than truck x.

that would be because of both gravity and friction. so     c
