The radius of the sphere is r=5.15 cm=0.0515 m, and its surface is given by

So the total charge on the surface of the sphere is, using the charge density

:

The electrostatic force between the sphere and the point charge is:

where
ke is the Coulomb's constant
Q is the charge on the sphere

is the point charge
r is their separation
Re-arranging the equation, we can find the separation between the sphere and the point charge:
Answer:
It's more habitable.
Explanation:
The atmosphere, calculated to equations, are a lot more pulled down.
Answer:
98.33 %
Explanation:
On an elliptical orbit, angular momentum will be conserved .
Angular momentum = I ω = mvR
So mv₁R₁ = mv₂R₂
= v₁R₁ = v₂R₂
where v₁ is velocity and R₁ radius in low orbit (perigee)and v₂ and R₂ is velocity and radius in high orbit ( apogee ).
Here R₁ = Radius of the earth , R₂ is distance between moon and earth.
R₁ / R₂ = 1/60
v₁ /v₂ = R₂ / R₁ = 60
v₂ / v₁ = 1 / 60
1 - (v₂ / v₁ ) = 1 -( 1 / 60)
(v₁ -v₂)/v₁ = ( 60-1 )/60
(v₁ -v₂)/v₁ x 100 = 5900/60 = 98.33 %
