hey ash ! just look at the solution.
look velocity is given so we can easily calculate momentum .I considered the mass of that particle to be'm'.
So momentum =1000m.
You have to change velocity in its SI units.
now wavelength=h/mv
this formula is from debroglie hypothesis.
after plugging all the values we get wavelength =6.626×10^-37/m.
The value of planck's constant is 6.626×10-34.
