Question

In the early universe and in stars, deuterium nuclei are produced from the combination of one proton and one neutron, with the release of a gamma ray. What is the charge on a deuterium nucleus in units of qe = 1.6*10-19 C?

Answer 1

Answer:

$Q = q_e = 1.6 \times 10^{-19} C$

Explanation:

As we know that charge is always conserved

so here we have

initial total charge = final total charge

also we know that gamma rays are chargeless and massless particles

so we have

charge on deuterium is given as

Q = charge on proton + charge on neutron - charge on gamma

so we have

$Q = 1.6 \times 10^{-19}$

$Q = q_e = 1.6 \times 10^{-19} C$
