Question

A particle having a mass of 1 mg has a velocity 1 Km / sec. Calculate the wavelength of the particle: (A) 6.626 × 10-28 cm (B) 6.626 × 10-29 cm (C) 6.626 × 10-30 cm (D) 6.626 × 10-31 cm

λ=(h/m v)=(6.626 × 10-27/10-3 × 105) ⇒ (6.626 × 10-27/102)=6.626 × 10-29 cm

Q. A particle having a mass of $1 m g$ has a velocity $1 K m /$ sec. Calculate the wavelength of the particle:

$6.626 \times 1 0^{- 28} c m$

$6.626 \times 1 0^{- 29} c m$

$6.626 \times 1 0^{- 30} c m$

$6.626 \times 1 0^{- 31} c m$

$λ = \frac{h}{m v} = \frac{6.626 \times 1 0 ^{- 27}}{1 0 ^{- 3} \times 1 0 ^{5}}$

$\Rightarrow \frac{6.626 \times 1 0 ^{- 27}}{1 0 ^{2}} = 6.626 \times 1 0^{- 29} c m$
