A 0.66 kg ball is moving with a speed of 100 m/s. The associated wavelength will be ($h = 6.6\times10^{-34}$ J s)
A
$6.6\times10^{-32}$ m
B
$6.6\times10^{-34}$ m
C
$1.0\times10^{-35}$ m
D
$1.0\times10^{-32}$ m
Detailed Solution
de Broglie relation: $\lambda = \frac{h}{mv}$
$\lambda = \frac{6.6\times10^{-34}}{0.66\times100}$
$\lambda = \frac{6.6\times10^{-34}}{66}$
$\lambda = 1.0\times10^{-35}$ m
$\lambda = \frac{6.6\times10^{-34}}{0.66\times100}$
$\lambda = \frac{6.6\times10^{-34}}{66}$
$\lambda = 1.0\times10^{-35}$ m
