The answer would be no. Both will have same charge, in both caes charge will reside on surface. In case of solid sphere it will be distributed evenly throughout. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
It’s obviously C since all the rest of the answers make sense except for C.
Answer: 4.86
Explanation:
sphere moment of Inertia Iₑ = (2/5)mrₑ²
Let the sphere of radius 1.59 cm be x
Let the spherical shell of radius 7.72 cm be y, so that
Iₑ(x) = 2/5 * m * 1.59²
Iₑ(x) = 2/5 * m * 2.5281
Iₑ(x) = 1.011m
Iₑ(y) = 2/5 * m * 7.72²
Iₑ(y) = 2/5 * m * 59.5984
Iₑ(y) = 23.84m
Also, the angular speed of the sphere's would be ωₑ(x) and ωₑ(y)
total k.e = rotational k.e + linear k.e
for sphere = ½Iₑωₑ² + ½mωₑ²rₑ²
For sphere x
{ωₑ²[ 1.011 + 1.59²]} =
ωₑ²(1.011 + 2.5281) =
ωₑ²(3.5391)
For sphere y
{ωₑ²[ 23.84 + 7.72²]} =
ωₑ²(23.84 + 59.5984) =
ωₑ²(83.4384)
If the ratio of x/y = 1, then
ωₑ(x)²(3.5391) / ωₑ(y)²(83.4384) = 1
ωₑ(x)²(3.5391) = ωₑ(y)²(83.4384)
[ωₔ(x)/ωₑ(y)]² = [83.4384] / [3.5391] ~= 23.5762
[ωₔ(x)/ωₑ(y)] = √(23.5762)
[ωₔ(x)/ωₑ(y)] = 4.86
B. Neutrons or Protons Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.)
