Question

Which particle has approximately the same mass as a proton?

Answer 1

Answer:

so we know that mass of proton and mass of neutron is almost same

Explanation:

mass of the proton is given as

$m_p = 1.66 \times 10^{-27} kg$

here we know that

mass of the neutron is given as

$m_n = 1.67 \times 10^{-27} kg$

in terms of amu we have

$m_p = 1.007 amu$

$m_n = 1.008 amu$

so we know that mass of proton and mass of neutron is almost same
