When a charged particle enters in a uniform magnetic field then its kinetic energy ..becomes?
When a charged particle enters a uniform magnetic field, its kinetic energy remains constant. This is because the magnetic field exerts a force perpendicular to the particle's velocity, which changes the direction of the particle's motion but does not work on it. As a result, the speed of the particle—and thus its kinetic energy—remains unchanged, leading to circular or helical motion.
A high-speed electron ejected from a nucleus durng radioactive decay is called a?
an alpha particle
What happens if the electron enters the magnetic field parallel to B?
If an electron enters a magnetic field parallel to the field lines (i.e., parallel to B), it will not experience any deflection or force due to the magnetic field. This is because the force on a charged particle moving parallel to a magnetic field is zero.
A particle with a mass of 6.64 x 10-27 kg and a charge of plus 3.20 x 10-19 C is accelerated from rest through a potential difference of 2.45 x 106 V The particle then enters a uniform 1.60-T magnetic?
The kinetic energy gained by the particle due to the potential difference can be calculated using the formula KE = qV, where q is the charge and V is the potential difference. The kinetic energy can then be equated to the work done by the magnetic field, given by W = qvBd, where v is the velocity, B is the magnetic field, and d is the distance traveled in the magnetic field. Combining these equations can help determine the speed of the particle as it enters the magnetic field.
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.
How does the magnetic field affect the speed of a particle?
The magnetic field can change the direction of a charged particle's movement, but it does not directly affect its speed.

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.
What is the scientific principle behind particle accelators?
particle accelerators work by accelerating a charged particle in a magnetic field where the lines of magnetic flux are such that the particle is accelerated into a circular path. This is so that the force produced by such a motion and magnetic field is perpendicular to both the lines of magnetic flux and the velocity of the particle. The stronger the magnetic field and the faster the particle is moving, the more of a force is required (i.e stronger magnetic field) to keep the particle accelerating. Only a charged particle is affected by a magnetic field so only charged particles can be used inside a particle accelerators (i.e protons and electrons.) neutrons have a charge of zero and are not affected by magnetic fields.
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
What is the speed of rotation of the magnetic field called?
The speed of rotation of the magnetic field is called magnetic flux. It is a measure of the flow of a magnetic field through a particular area.
Which of the two charged particles of the same mass but different velocity will be deflected the most in magnetic field and why?
The charged particle with the higher velocity will be deflected the most in a magnetic field. This is because the magnetic force experienced by a charged particle is directly proportional to its velocity. Therefore, a higher velocity particle will experience a greater magnetic force and be deflected more.
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.

If an electron enters a magnetic field parallel to the field lines (i.e., parallel to B), it will not experience any deflection or force due to the magnetic field. This is because the force on a charged particle moving parallel to a magnetic field is zero.
How many nucleons does an alpha particle contain?
An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
