Answer:

The required ratio is 1.99.

Explanation:

We need to find the atio of speeds of a proton and an alpha particle accelerated through the same voltage.

We know that,

eV=\dfrac{1}{2}mv^2

The LHS for both proton and an alpha particle is the same.

So,

\dfrac{v_p}{v_a}=\sqrt{\dfrac{m_a}{m_p}} \\\\\dfrac{v_p}{v_a}=\sqrt{\dfrac{6.64\times 10^{-27}}{1.67\times 10^{-27}}} \\\\=1.99

So, the ratio of the speeds of a proton and an alpha particle is equal to 1.99.
