A high-speed electron ejected from a nucleus durng radioactive decay is called a?
an alpha particle
When do charged particles accelerate in a magnetic field?
A charged particle is accelerated in magnetic field if it has a velocity. F = Q v x B, where v x B is cross-product of speed and magnetic flux vectors. According to Newton F = ma where you can find the acceleration if you know the mass.
At what speed do alpha particles travel?
Alpha radiation, like any other form of electromagnetic radiation, travels at the speed of light (300 000 000 metres per second)
How much force can an alpha particle exert?
This depends on the velocity, or temperature, of the alpha particle. The faster the particle goes, the higher its temperature, and the more energetic it is. When we are dealing with atoms and subatomic particles, temperature and velocity are pretty much measurements of the same thing. Most alpha particles emitted from large radioactive atoms have energies in the range of 3 to 7 MeV (million electron volts). Alpha particles from the decay of the heavier, man-made atoms can be more energetic yet. 5 MeV would mean that the particle is going about 15,000 km/s, or about 5% of the speed of light. At that speed, the alpha particle can be absorbed by a piece of thin paper. They are not horribly dangerous, if the particles are outside you. But if they are emitted from something inside you, they can be very destructive because they can alter living cells. It should be noted that an alpha particle is essentially the same thing as a Helium-4 nucleus. The difference is that the alpha particle came from nuclear decay, and is moving.
Why are alpha particle tracks observed in a cloud chamber much shorter than beta particle tracks though they emerge from a radioactive sample with almost the same speed?
Alpha particles have a mass of about 4 and a charge of +2, while beta particles have a mass of about 5x10-4 and a charge of -1. As such, the alpha particle interacts much more easily than the beta particle, and spends its energy more quickly.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
What are three things that a magnetic field may do to moving charged particles?
Accelerate the particle but not beyond C, the speed of light Decelerate the particle Divert the particle's path.
Why force exerted by a magnetic field on stationary elctric dipole is zero?
The force on a charge by a magnetic field is given by F = Bq v sin@ v - the speed of the charged particle with charge q. B - magnetic field induction in tesla. @ is the angle between the velocity vector and magnetic field vector. As dipole is stationary, the speed of charges is zero. So the force = 0 Hence the result.
An alpha particle Helium travelling at right angles to magnetic field of 0.2 weber per m sq experience a force of 3.84 x 10-14 N.What is the speed of alpha particle?
The force acting on a moving charge q in a magnetic field B is given by F = qvBsinθ Substituting the value of F,q, and sinθ (The value of sinθ = 90o ,which is equal to 1) We get ,v = F/qBsinθ = 3.84 x 10-14 /2 x 1.6 x 10-16 x 0.2 = 384 x 105 /2 x 16 x 2 = 6 x 105 ms-1 The speed of alpha particle is 6 x 105 ms-1
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.

What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
At what speed do alpha particles travel?
Alpha radiation, like any other form of electromagnetic radiation, travels at the speed of light (300 000 000 metres per second)

What is meant by Slip of an induction motor?
Slip is referred to as the difference between the speed of the rotor and the speed of the rotating magnetic field in the stator of the induction motor. Speed of the rotor=n(1-s) Speed of the rotating magnetic field= f/p
