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

The force on a charged particle due to a magnetic field is given by the equation F = qvB, where q is the charge of the particle, v is its velocity, and B is the magnetic field strength. In this case, the force is given as 3.84 x 10^-14 N, the charge of an alpha particle is 2e (where e is the elementary charge), and the magnetic field strength is 0.2 T. Solving for v gives v = F / (qB). Plugging in the values, we get v = (3.84 x 10^-14) / (2(1.6 x 10^-19)(0.2)) = 1.2 x 10^5 m/s.

The nucleus of a helium atom is called?
The nucleus of a helium atom is called the alpha particle, which consists of two protons and two neutrons. It is positively charged and accounts for most of the mass of the helium atom.
What is another name for beta particle?
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
What is another name for an alpha particle?
Helium nucleus.
An alpha particle has the same structure as which nucleus?
An alpha particle has the same structure as a helium nucleus, consisting of two protons and two neutrons.
What will an alpha particle change into when it absorbs two electrons?
When an alpha particle absorbs two electrons, it will become a helium atom. This is because an alpha particle is essentially a helium nucleus consisting of two protons and two neutrons, and by also gaining two electrons, it will form a stable helium atom with two protons, two neutrons, and two electrons.
What is an alpha particle equivilent to?
An alpha particle is equivalent to a helium-4 nucleus, or a helium-4 ion. A difference is that an alpha particle has a certain amount of energy associated with it, so it can said to be fast or hot. The energy is measured in thousands or millions of electron volts (keV or MeV).
What radioactive particle is the size of a helium nucleus?
alpha particle
What element has atomic structure similar to an alpha particle?
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
Why is an alpha particle sometimes referred to as a helium nucleus?
An alpha particle consists of two protons and two neutrons, which is the same composition as a helium nucleus. This similarity is why an alpha particle is often referred to as a helium nucleus.
The nucleus of a helium atom is called?
The nucleus of a helium atom is called the alpha particle, which consists of two protons and two neutrons. It is positively charged and accounts for most of the mass of the helium atom.
Hydrogen is to a proton as helium is to?
an alpha particle
What is alpha particle identical to?
Helium nuclei.
The nucleus of a helium atom is identical to what?
The nucleus of a helium atom is identical to an alpha particle, which consists of two protons and two neutrons.
Is helium paramagnetic?
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
Releases a helium particle?
A balloon filled with helium will leak Helium particles this way and that, you silly monkey <3
Is an alpha particle is identical to the nucleus of a?
An alpha particle is identical to the nucleus of Helium atom
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
