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

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
