According to de Broglieâs equation λ=(h/mv) =(6.626 × 10-34 × 3600/0.2 × 5) λ=2.385×10-30 m

Q. The de Broglie wavelength associated with a ball of mass $200 g$ and moving at a speed of $5$ metres/hour, is of the order of ( $h = 6.625 \times 1 0^{- 34} J s$ ) is

$1 0^{- 15} m$

$1 0^{- 20} m$

$1 0^{- 25} m$

$1 0^{- 30} m$

According to de Broglie’s equation
$λ = \frac{h}{m v}$
$= \frac{6.626 \times 1 0 ^{- 34} \times 3600}{0.2 \times 5}$
$λ = 2.385 \times 1 0^{- 30} m$
