from the sun? My Science exam is MONDAY and I need the answer to study from!

What do you mean? Do you mean what planet has the weakest gravitational pull itself? That would be the smallest one, Mercury. Do you mean which one has the weakest pull "on it" from some outside source, like the sun? Then the farthest one, Neptune.
As for tiny particles being released from the sun:
Sunlight
Radiation
Heat
Neutrinos
I mean is there a word bank here?
I was unable to reply, your email hasn't "been confrimed yet" so:
Ahh! that helps
Of those 4 choices, it's the furthest away which is Pluto (actually no longer a planet, that's why I said Neptune before).
as for the particles:
Auroras
Caused by particles interacting with the earth's magnetic field. Although an argument can be made for solar eclipses since without particles (photons) there would be no eclipse.
Good luck!!

Since gravity is a direct function of mass, then the planet with the weakest gravity would be the one with the smallest mass.
Since Pluto is no longer a "planet", the smallest remaining planet is Mercury.
The second question, what is caused by tiny particles being released from the sun, I think you are referring to the solar wind. This is composed of charged particles ejected from the sun and moves through space in all directions from the sun.
Not sure what you mean by "what is caused by" in your question.
Perhaps you should reword your question so we can answer it for you.
Or better yet, why not do some research on your own - wikipedia or www.astronomy.com are both great places to look for astronomical info.

Gravity is the lone rigidity which does no longer have an opposite. The magnetic rigidity, working example has a 'North' and a 'South'. different forces will attraction to or repel in keeping with those 2 opposite element. Gravity on my own has purely an attracting element. For the 2nd area of your question...specific, a proton has a pull even on Pluto. The gravitational rigidity has 2 components. those are the mass and the area of each and every physique. So a proton say in area between Earth and the moon is inspired by potential of Pluto - as a results of potential of an infinitesimally small quantity.

Just adding to the others who have provided guidance.
Wikipedia is a good source for that kind of stuff.
Many of the particles that leave the sun and make up the Solar Wind, are charged particles. They get trapped in Earth's magnetic filed and eventually fall down along the lines of our magnetic field (therefore, mostly towards the magnetic poles).
When the charged particles reach the upper atmosphere, it is exactly like an electric current going through the very-low-pressure gas in a fluorescent tube. The charged particles ionise the gas atoms which then glow (Aurora).

The planet farthest away from the sun has the weakest pull on it.
Gravity falls off at 1/r^3 wher r is the distance. Nepture is the most distant planet (since Pluto is no longer a planet) - so the answer is Neptune,
