Question 10

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

(Use: charge of a proton = 1.60 × 10-19 C, mass of a nucleon = 1.67 × 10-27 kg)

A

4.1×107 C kg−14.1 \times 10^7\text{ C kg}^{-1}4.1×107 C kg−1

B

5.5×107 C kg−15.5 \times 10^7\text{ C kg}^{-1}5.5×107 C kg−1

C

9.6×107 C kg−19.6 \times 10^7\text{ C kg}^{-1}9.6×107 C kg−1

D

7.2×107 C kg−17.2 \times 10^7\text{ C kg}^{-1}7.2×107 C kg−1
