It is false. A gamma ray has no charge, but it is an electromagnetic wave, not a particle.

What are the masses of alpha beta gamma?
The alpha particle basically has the mass of a helium atom, since it is a helium nucleus. The beta particle has the mass of an electron - a beta particle is either an electron or an anti-electron. The gamma ray has no rest mass, since it moves at the speed of light. However, it can have a fairly high energy, and therefore an associated mass. The mass varies in this case; that is, gamma rays can have different energies, and therefore different masses.
Do gamma rays have physical mass?
No. Gamma rays are waves, as part of the electromagnetic spectrum, and have no mass at all. A gamma ray is a form of electromagnetic energy. As such, it is said to have a rest mass of zero. A gamma ray, being electromagnetic energy, has some "particle-like" properties, as does other photonic radiation. But it moves at the speed of light in a vacuum and is generally said to be massless.
What is the difference of alpha beta and gamma radiation?
These are types of both particulate and electromagnetic radiation, and alpha and beta are the former while gamma is the latter. Let's look at each one in brief. An alpha particle is a pair of protons and a pair of neutrons all hooked together. It's a helium-4 nucleus, and it's particulate radiation. A gamma ray is electromagnetic radiation (an electromagnetic ray) of very high frequency and energy (which also means very short wavelength). A beta particle is one of two types of particles, either a beta plus particle or a beta minus particle. The beta minus particle is an electron, and a beta plus particle is a positron, or anti-electron (antimatter). Beta radiation is particulate radiation. What is key to understanding these guys is how they are formed. Use the links below to the three questions that specifically speak to the characteristics of each of these types of radiation. These questions are already posted and answered here; no need for repetition.
What can be said about the speed of a particle if the net work done on it is zero?
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
Is it true or false that a gamma ray is a very high-speed particle with no charge?
True. A gamma ray is a high-energy photon, and thus moves at the speed of light. And, like all photons, it has no charge.
A gamma ray is a very high speed particle with no charge?
Sort of. A gamma ray is a photon, which is a particle/wave moving at the speed of light, because it is light.Photons are the gauge particles for the electromagnetic force, but they don't carry an electric charge themselves.
What is the relative charge of gamma particles?
The gamma particle's symbol is the lowercase Greek gamma, the velar, which looks like a lower case western v, but the base has a narrow loop, and the left top has a curved serif. In print, it looks like a Y, shifted down as if it were a lower case letter with a descender. We can't represent it here on Answers.com, but the Related Link below will take you to WikiPedia where you can see a representation of it. The charge of a gamma particle is that of the photon, which is zero.
What is invariance of charge?
Invariance of charge refers to the independence of electrostatic potential of a particle from its speed. That is, the charge of a particle does not vary with its speed. In other words charge is not relativistic as opposed to relativistic quantities such as mass, energy etc.
If speed of particle remains constant then it means that no unbalanced force act on it Is it true of false?
true

Why gamma rays travel at the speed of light?
Because they are made up of photons, which have no rest mass. Having no rest mass, they are the only particle that is capable of traveling at the speed of light per the lorentz transformation.

What form of nuclear radiation gives off either particles emery that have no mass and no charge?
X-Ray and Gamma are photons. Photons have no mass and no charge. Well, sort of... Photons have no mass at rest state. Problem is, they don't sit at rest state. They move at the speed of light. At that speed there is an infinite mass multiplication effect from the Lorentz transformation, 1 / (1 - (1 - v2/c2)-1/2). Take a particle with no mass and multiply that mass by infinity and you get - well, officially, its indeterminate - unless you start talking about limits - then you get some mass. Bottom line - there is no particle with no mass, unless you happen to also be moving at the speed of light relative to the particle, and that would require infinite energy.
Which radiation particle carries 2 neutrons per particle?
An particle of alpha-radiation consists of two protons and two neutrons. It is a highly charged particle and is thus highly ionising. It is therefore highly dangerous. Because of its size, it penetrates very little, being stopped even by a thin sheet of paper. The other forms of radiation are beta-radiation and gamma-radiation. Beta-radiation consists of a high-speed electron, whereas gamma-radiation is a high-energy electromagnetic wave.
Does a particle need to have an electrical charge to be used in a particle accelerator?
Yes, a particle used in a particle accelerator must have a charge to be useful in the device. Particle accelerators we use in high energy physics to investigate things all work by applying a moving or shifting magnetic field to accelerate charged particles. We speed these particles up by repeatedly "hitting" them with a magnetic field. Uncharged particles will not respond to this, and canot be used in the devices.
Why do gamma rays travel at the speed of light?
Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.
