What is the ratio of specific charge of electron and alpha particle?
The ration of the “e//m” (specific charge) values of an electron and an alpha-“particle” is.
(d) (e/m)e(e/m)α=e/me2e/4×1836me.
What is the specific charge ratio of alpha particle?
$alpha $-particle also called as helium is a positively charged particle consisting of two protons and deuterons having a charge +2 and mass 4 amu whereas deuteron has a mass 2 amu which is why it is also called two hydrogen and has a charge +1e. Hence the ratio of specific charges is
1:1
for helium and deuteron.
What is the ratio of mass of proton and alpha particle?
| alpha particle-proton mass ratio | Numerical value 3.972 599 690 09 | Standard uncertainty 0.000 000 000 22 | Relative standard uncertainty 5.5 x 10 – 11 | Concise form 3.972 599 690 09(22) |

What is the ratio of specific charge?
(D) 1:1. Hint: Specific charge of a particle is defined as
the ratio of the charge on the particle to the mass of the particle
. Both proton and alpha particles are positively charged species. A proton is a positively charged species found in the nucleus of the atom.
Which is the highest specific charge?
An electron
has the greatest specific charge of any particle. To beat it you would either need more charge for the same mass or else a lower mass and the same charge.

What is the specific charge of electron?
Some disciplines use the charge-to-mass ratio (Q/m) instead, which is the multiplicative inverse of the mass-to-charge ratio. The CODATA recommended value for an electron is
Qm = −1.75882001076(53)×10

.
Is mass of proton and deuteron same?
Whose Mass is Greater, Proton or Deuteron. Ans-
The mass of a deuterium atom is greater than that of a proton
; this is because of the presence of a neutron in the deuterium. Also, the mass of a neutron is a little bit more to that of a proton.
Who is the father of neutron?
James Chadwick, in full
Sir James Chadwick
, (born October 20, 1891, Manchester, England—died July 24, 1974, Cambridge, Cambridgeshire), English physicist who received the Nobel Prize for Physics in 1935 for the discovery of the neutron.
What is the e/m value of alpha particle?
Alpha particle is a helium nucleus which consists two protons and two electrons. It has +2 charge and the mass of four protons. So the alpha particle has the least E/M because of its large mass. You can see that its E/M is equal to
1/2 time E/M of a proton
.
What is the formula for specific charge?
The specific charge of a particle is the ratio of its charge to its mass, given in coulombs per kilogram (C kg–1). To calculate specific charge,
you just divide the charge in C by the mass in kg.
What is the E by M specific charge ratio of proton and neutron?

.
Which has highest E M ratio?
Overall the highest value of e/m ratio is for
H+ ion
.
Which has highest specific heat?
Water
has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.
