Answer:
D) 30°
Explanation:
This is in accordance to the Gauss Law which states that, <em>the electric flux through any closed surface is equal to the total charge enclosed by the surface divided by the permittivity of free space.</em>
Mathematically given as:
where
θ = the angle between the electric field lines and area vector normal to the surface.
When the area vector has formed an angle of 60° then the plane is at 30° and we know <em>cos 60° = 0.5</em>

The Jovian planets contain large percentage of Gases its because they are formed outside of what they called as frost line where temperature is low enough for ice condensation unlike terrestrial planets formed close to the sun where the temperature is very appropriate for metal and rock to condense.
The number of molecules in each atom in the reaction.
Answer:
Explanation:
An atom is constructed of three different particles known as electrons, protons and neutrons.
These particles have different mass and charges and are responsible for various characters than an atom posses.
An electron has a negative charge, a proton has positive charge and charge of neutron is neutral. Equal number of electrons and protons are present in an atom that make it electrically neutral but different conditions can occur if we remove these particles from an atom.
1 : Model of an ionized atom - an ionized atom is one which has some net charge on this. It can be either a positive charge or a negative charge.
If we need to sketch the model of an ionized atom then one should either keep the number of electrons less or proton.
2: Model of radioactive atom : A radioactive atom is one an unstable atom and has access of energy in its center. It can be caused by adding either neutrons or protons.
