Structure of Atom - Result Question 24
####26. A $0.66 kg$ ball is moving with a speed of $100 m / s$. The associated wavelength will be $(h=6.6 \times 10^{-34} Js)$ :
[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) $\lambda=\frac{h}{m v}=\frac{6.6 \times 10^{-34}}{0.66 \times 100}=1 \times 10^{-35} m$
