50 μC of negative charge is placed on an insulating pith ball and lowered into a insulating plastic container, suspended from an insulating thread attached to the lid of the box. After the box is entirely sealed, the electric flux through the sides of the box is: a. 5. 65 Times 10^6 N m^2/C.
b. 5. 65 Times 10^5 N m^5/C.
c. -5. 65 Times 10^6 N m^2/C.
d. 50 x 10^-6 N m^2/C.
e. -5.65 Times 10^5 N m^2/C.
f. Can't tell unless the dimensions of the box are given.

c.

Explanation:

The calculation of the electric flux through the sides of the box is shown below:-

Negative charge in insulating pitch ball,

Now, we are placing the values into the formula which is here below:-

=

Therefore we divided the negative charge by permittivity to reach out the electric flux through the sides of the box.

0.19 m/s and 0.45 m/s

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.
