Structure of Atom - Result Question 24

####26. A $0.66 k g$ ball is moving with a speed of $100 m / s$ . The associated wavelength will be $(h = 6.6 \times 10^{- 34} J s)$ :

[2010]

(a) $1.0 \times 10^{- 32} m$

(b) $6.6 \times 10^{- 32} m$

(c) $6.6 \times 10^{- 34} m$

(d) $1.0 \times 10^{- 35} m$

Show Answer

Solution:

(d) $λ = \frac{h}{m v} = \frac{6.6 \times 10^{- 34}}{0.66 \times 100} = 1 \times 10^{- 35} m$
