Question 24

What is the specific charge of a   614C^{14}_{\ \ 6}\text{C}  614​C nucleus?

Use the following values:

  • elementary charge, e=1.60×10−19 Ce = 1.60 \times 10^{-19}\text{ C}e=1.60×10−19 C
  • unified atomic mass unit, u=1.66×10−27 kgu = 1.66 \times 10^{-27}\text{ kg}u=1.66×10−27 kg
A

6.88×106 C kg−16.88 \times 10^6\text{ C kg}^{-1}6.88×106 C kg−1

B

4.13×107 C kg−14.13 \times 10^7\text{ C kg}^{-1}4.13×107 C kg−1

C

9.64×107 C kg−19.64 \times 10^7\text{ C kg}^{-1}9.64×107 C kg−1

D

2.25×108 C kg−12.25 \times 10^8\text{ C kg}^{-1}2.25×108 C kg−1
