Any elementary particle with an electrical charge (sort of circular answer); How about ... it's either an electron (negative) or a proton (positive). There are others, but you'll probably never come in contact with them.
No, according to the theory of relativity, it is impossible for any particle with mass to reach or exceed the speed of light. Accelerators can increase the speed of particles to high fractions of the speed of light, but they cannot exceed it.
this never has the answers i need!
you are right charges can never be at rest but the columbs law and electric field and other topics are being studied just imaginary, suppose that when charges are at rest they must emit a field which is called as electric field.
Sure! It would be the god particle, but it's never been found, people are looking. ^ Indian philosophers have struggled with this concept before the time of Christ. They believe all things consist of the same element, but naming something refers to it as objective always having a missing puzzle piece. This creates an infinite regress. The only way to correctly identify this particle is by referring to it as subjective, saying that it just "is", i.e. the God particle.
then we would never know about charge on it.

This particle doesn't exist.

The hypothetical (since it has not yet been observed) messenger particle for gravity is called the graviton. Whilst the particle has never been seen before we do know a few things about it on theoretical grounds: -We know the graviton is massless because the range of gravity is infinite and follows an inverse square law. Also the influence of gravity travels at the speed of light and only massless particles are allowed to travel at the speed of light. -We know the graviton couples to every other particle. This is true simply because it couples to energy (or more specifically to representations of the Lorentz group) and every particles carries energy. -We know a graviton couples to itself, this is because of the non-linearity of gravity, and the group structure of the Lorentz group (which governs gravity). -We know the graviton is a spin-2 particle because gravity arises from local Lorentz invariance of the Universe (this one is a bit technical) which requires a tensor gauge current.
B. Never associated with charged particles. Matter waves, as described by quantum mechanics, are associated with particles, whether they are charged or uncharged.
Linus Torvalds has never charged anything for Linux.
A photon is a discrete particle (having zero mass, zero charge, and an indefinate life span explainable only by quantum physics) and can travel at the speed of light; a "material particle" can only travel at speeds lower than the speed of light.
Someone can be charged with felony burglary even if they were the driver and never went in to the house because they helped in the commission of that crime.
A photon is said to be "massless", meaning that it has no REST MASS (of course, having energy, it also has an equivalent mass).In a vacuum, a photon can ONLY move at the so-called speed of light (about 300,000 km/second). "Regular" particles can ONLY move at sub-light speed. They can get close to the speed of light, but never quite reach it.
