What are the units of specific charge?
The specific charge of a charged object is its charge divided by its mass. As the unit of charge is the coulomb (C) and the unit of mass is the kilogram (kg), the unit of specific charge is the coulomb per kilogram (C kg–1).
What is specific charge and its unit?
The specific charge is defined as a charge by mass ratio i.e e/m. The charge on an electron (e) = 1.602 X 10-19C. The mass of the electron (m) = 9.1×10−31Kg. Specific charge = Charge (e) / Mass (m)
What is the meaning of specific charge?
1 : a charge against specific identifiable property that is essentially the same in effect as a mortgage. 2 : the ratio of the electric charge on a particle to its mass.
Which of the following has highest specific charge?
positron
What is the specific charge of alpha particle?

What is the specific charge of Proton?
The specific charge of a proton is 9.6* 10^7Ckg^-1.
Which of the following is an arrangement of increasing value of e m?
The increasing order for the values of e/m (charge/mass) for the electron (e), proton (p), neutron (n) and alpha particle (α) is: A.e, p, n, α
Which has highest E M ratio?
– As we know that Specific charge = e/m. Where, m = mass and e = charge. -Hence, we can say that the correct option is (b), that is the e/m ratio is maximum for H+.
What is E M ratio?
The e/m ratio. Objective To measure the electronic charge-to-mass ratio e/m, by injecting electrons into a magnetic field and examining their trajectories. We also estimate the magnitude of the earth’s magnetic field.
Why do we calculate EM ratio?
The measuring the e/m ratio of an electron was very important so physics could gain a better understanding of this particle. The measuring the e/m ratio of an electron was very important to physics at the beginning of the 1900s. It allowed scientists to gain a better understanding of this newly discovered particle.
