Question

The ratio of the absolute masses and the charges of a proton to a neutron respectively are:

• A. $1,1.6\times {10}^{-19}$
• B. $1.6\times {10}^{-19},1$
• C. $\infty ,1.6\times {10}^{-19}$
• D. $1,\infty$

Answer 1

The correct option is D $1,\infty$

The ratio of the absolute mass of a proton and neutron is 1 since both have nearly the same mass.
The ratio of the charges of a proton and a neutron = $\infty$ (since mass of neutron is 0)
