λ = h / MV

M = h / λV

-----------------------------

------------------------------------------------

M --- mass of proton

h --- planck's constant

λ --- Wave length

V --- Velocity

--------------------------------

--------------------------------------------------

λ = 3.6 A⁰ = 3.6 × 10⁻¹⁰ m

h = 6.626 × 10 ⁻³⁴

V = 3 × 10⁸ m/s

---------------------------------

--------------------------------------------------

∴ M = ( 6.626 × 10 ⁻³⁴ ) / [ ( 3.6 × 10⁻¹⁰ ) × ( 3 × 10⁸)]

= 6. 135 × 10⁻³³ kg //
