A metal dome has an electric field surrounding it, with the electric field pointing to the right of 6.5x106 N/C at a certain location. An unknown charge is then placed at this location. What will be the type and size of this unknown charge if it feels a force of 10250 N to the left?

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

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.
