In an experiment analyzing the properties of various ions, a physicist compares a fully ionised carbon-12 (0612C^{12}_{\phantom{0}6}\text{C}0612C) nucleus with a singly ionised helium-4 (24He+^{4}_{2}\text{He}^{+}24He+) ion.
What is the value of the ratio:
specific charge of the carbon-12 nucleusspecific charge of the helium-4 ion \frac{\text{specific charge of the carbon-12 nucleus}}{\text{specific charge of the helium-4 ion}} specific charge of the helium-4 ionspecific charge of the carbon-12 nucleus(Assume the mass of an electron is negligible compared to the mass of a nucleon.)
