Final answer:

The charge distributed uniformly over the volume of an insulating sphere with a radius of 5.00 cm is 19.08 * 10^6 C/m^3.

Step-by-step explanation:

In order to find the charge distributed uniformly over the volume of an insulating sphere, we need to use the formula:

Charge = Volume * Charge density

The volume of a sphere is given by the formula:

Volume = (4/3) * pi * r^3

Substituting the given radius of 5.00 cm (0.05 m) into the formula, we get:

Volume = (4/3) * pi * (0.05 m)^3 = 5.24 x 10^-4 m^3

The charge density is the total charge divided by the volume. Since the charge is distributed uniformly, the total charge is equal to the charge density times the volume:

Total charge = Charge density * Volume

Substituting the given total charge of 10.00 μC into the formula, we get:

10.00 μC = Charge density * 5.24 x 10^-4 m^3

Solving for the charge density, we find:

Charge density = 10.00 μC / 5.24 x 10^-4 m^3 = 19.08 * 10^6 C/m^3

Therefore, the charge distributed uniformly over the volume of the insulating sphere is 19.08 * 10^6 C/m^3.
