λ = h / p = De Broglie wavelength of a massive particle travelling at a momentum of p.
λ = 0.0005 * 10⁻⁴° meters ??? is some thing missing in the question ?
=> p = 6.626 * 10⁻³⁴ J-sec / 0.0005 * 10⁻⁴° meter = 1.3252 * 10¹° kg-m/sec
=> mass = p / m = 6.6626 * 10⁷ kg
==========================
Perhaps λ = 0.0005 * h
in that case,
p = h / λ = 2000 kg-m/sec
then mass m = 2000 kg-m/sec / 200 m/sec = 10 kg
