Single Choice

Which of the following particles have nonzero $$e/m$$ ratio?

ANeutron
BNeutrino
CPositron
Correct Answer
DNeutral meson

Solution

$$\text{Specific charge}=\frac{e}{m}$$

Where, e = charge

m = mass
The charge possessed by the neutron,neutrino and neutral meson is zero so their $$\frac{e}{m}$$ ratio will also be equals to zero.
But the positron is having a charge $$+1$$. So its $$\frac{e}{m}$$ ratio is non zero.
Hence option C is correct.
