Is alpha particle same as proton radius?

A proton and an alpha particle having the same kinetic energy are moving in circular paths in a uniform magnetic field. The radii of their circular paths will be equal.

What is the radius of an alpha particle?

1.67824 femtometers
The researchers measured the charge radius of the α particle to be 1.67824 femtometers.

What is the ratio of velocity of proton and alpha particle?

Therefore, the velocity of the proton is four times the mass of the alpha particle.

What is the ratio of the kinetic energy if both a proton or an alpha particle moving with same velocity enters perpendicular to the B?

1
Which suggests the Kinetic energy of both the particles is the same. Hence the ratio of kinetic energy of an alpha particle and a proton is 1.

What is the ratio of Debroglie wavelength of proton and alpha particle of same energy?

The ratio of de Broglie wavelength of an α- particle and a proton of same kinetic energy is. 1:2.

What is the ratio of charge by mass ratio of proton and alpha particle?

Alpha particle is a helium nucleus that comprises two protons and two neutrons, and the charge is twice the charge of the proton while the mass is around four times greater. Mass of helium = 4m. Therefore, the charge to mass ratio of an alpha particle is approximate twice the charge to mass ratio of a proton.

What is EM ratio of alpha particle?

e/m for electron is 1/0 (as electron has negligible mass), for proton is 1/1, for neutron is 0/1, and for alpha particle is 2/4 or 1/2.

How do you calculate alpha particles?

So first look at the father nucleus and list its number of protons and its atomic weight. Step 3) Now from number of neutrons subtract 2 and from number of protons subtract 2 as an alpha particle has 2 neutrons and 2 protons and in an alpha decay an alpha particle will always form in case of any any father nucleus.

What is the radius of an a particle?

The radius of an α-particle moving in a circle in a constant magnetic field is half of the radius of an electron moving in circular path in the same field. The de Broglie wavelength of α-particle is x times that of the electrons.

What is the ratio of de Broglie wavelength of proton and alpha particle if they are accelerated?

22 ​:1.

How do you find the proton ratio?

We can determine the number of neutrons by subtracting the number of protons, 82 , from the mass number, 206 . The nucleus of a lead-206 isotope has 82 protons and 124 neutrons. The neutron:proton ratio is 124:82 , which can be reduces to 62:41 .

What is the ratio of radius to charge of alpha particle?

Radius=charge×magneticf ieldmomentum We know that radius is inversely proportional to charge So Radius of alpha particle will be half of radius of proton Hence ratio of Radii =1:2

How do alpha particles and a proton enter the magnetic field?

A proton and an alpha particle enter the same magnetic field which is perpendicular to their velocity and have the same kinetic energy. Given, mα​=4mp​

What is the kinetic energy of a proton and alpha particle?

A proton and an alpha particle enter the same magnetic field which is perpendicular to their velocity and have the same kinetic energy. r= qBqB2m . . . . . . . .

What is the ratio of R_P/R_alpha to Q_Alpha?

So, very easily, R_p/R_alpha= q_alpha/q_p =2/1.Since a proton has one unit of positive charge, whereas an alpha particle, which is a helium nucleus has two unit of positive charge. So, the ratio is 2:1. If it’s this that you wanted to know,see the solution, but if you meant something else, frame that question carefully and request for my answer.
