A particle of mass $1 mg$ has the same wavelength as an electron moving with a velocity of $3 \times 1 0^{6} ms^{- 1}$ . The velocity of the particle is (mass of electron $= 9.1 \times 1 0^{- 31} kg$ )NEET 2008 (Mains)

Options:

Answer:

Solution:

Same momentum of both particles $1 \times 1 0^{- 3} \times v = 9 \times 1 0^{- 31} \times 3 \times 1 0^{6} v = 2.7 \times 1 0^{- 18} m / s$
