A point charge q is located at the origin surrounded by a spherical medium with dielectric constant ε and a radius of R. Outside the spherical medium is vacuum. A second point charge q is located at a distance d >> R from the origin. Calculate the Coulomb’s force the second charge experiences

Explanation:

According to Coulomb's law, the force of attraction between two charges, q1 and q2 is directly proportional to the product of the charges and inversely proportional to the distance separating them.

Since d > R

the second charge will experience a force

Where K = 9.0 x 10⁹ N.m²/C²

c) up

hope this

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
