what is charge to mass ratio of proton and alpha particles ?

Answers

Answered by komalsinghrajput

"Alpha partical is a helium nucleus containing two protons and two neutrons so it's charge is twice of the proton's charge while the mass is about 4 times greater."

Naruto08: yes

Naruto08: thank you buddy.

Naruto08: but what is the charge to mass ratio of proton ?

komalsinghrajput: the charge-to- mass ratio of an electron is -1.76

komalsinghrajput: 1.76×1011 coulomb/kg while the charge-to- mass ratio of a proton is 9.58× 107 coulomb/kg.

komalsinghrajput: hope it help

komalsinghrajput: please mark brainlist.

Naruto08: i dont know how to mark it brainlist.

Naruto08: if i had known about that i would have done it first only

komalsinghrajput: thanks

Originally Answered: What is the ratio of the specific charge of the proton and alpha particles? Alpha particle is a helium nucleus containing two protons and two neutrons so its charge is twice of the proton's charge while the mass is about 4 times greater.

varunmourya: Hi there,

Here's an easy way to solve this.

Let charge of proton be +e, then charge of alpha particle will be +2e. Similarly let mass of proton be m, then mass of alpha particle will be 4m.

Now, specific charge = charge / mass of the substance.

For proton, specific charge = e/m

For alpha particle, specific charge = 2e/4m

Therefore there ratio is : (e/m) * (4m/2e) = 2:1

varunmourya: your ans
