negative electric charge वाक्य

If it encountered ordinary mass, then both could " cancel out " each other's existence, in the same way that positive and negative electric charges can cancel out each other's effects.
A normal uncharged piece of matter has equal numbers of positive and negative electric charges in each part of it, located close together, so no part of it has a net electric charge.
Paul Dirac observed in 1931 that, because electricity and magnetism show a certain symmetry, just as negative electric charges can be observed without the opposing charge, isolated South or North magnetic poles should be observable.
So, said in really raw words : a neutron emits ( on its own or there is a reason ? ) a W-boson, which " extracts " one unit of negative electric charge from the neutron, and the neutron is transformed in a proton.
Many early scientists attributed the magnetism of lodestones to two different " magnetic fluids " ( " effluvia " ), a north-pole fluid at one end and a south-pole fluid at the other, which attracted and repelled each other in analogy to positive and negative electric charge.

Also in 1936, Anderson and his first graduate student, Seth Neddermeyer, discovered the muon ( or'mu-meson', as it was known for many years ), a subatomic particle 207 times more massive than the electron, but with the same negative electric charge and spin 1 / 2 as the electron, again in cosmic rays.
In the field line description, electric field lines begin only at positive electric charges and end only at negative electric charges .'Counting'the number of field lines passing through a closed surface, therefore, yields the total charge ( including bound charge due to polarization of material ) enclosed by that surface divided by dielectricity of free space ( the vacuum permittivity ).
