The weapon used by the jawa surrounds r2-d2 with a strong electric field, which is created by a large imbalance of electrons chemical bonds neutrons the force

If there is balance between the positively charged protons and the negatively charged electrons, the two chargers are neutralized. an imbalance of protons and electrons leads to imbalance of charges. electrons are then able to move, resulting to the  formation of an electric field. 

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
