Question

the mass and charge of a beta particle are, respectively, _______.
o 4 amu and 2+
o $\frac{1}{1840}$ amu and 1-
o 0 amu and 1-
o $\frac{1}{1840}$ amu and 1+

Explanation:

A beta - particle is an electron or a positron. An electron (the most common type of beta - particle) has a mass of approximately $\frac{1}{1840}$ amu and a charge of 1-.

Answer:

$\frac{1}{1840}$ amu and 1-
