The correct answer is:
$1.0 \times 10^{-35} \mathrm{~m}$
From de-Broglie equation,
$$
\lambda=\frac{\mathrm{h}}{\mathrm{mv}}=\frac{6.6 \times 10^{-34}}{0.66 \times 100}=10^{-35} \mathrm{~m}
$$
$$
\lambda=\frac{\mathrm{h}}{\mathrm{mv}}=\frac{6.6 \times 10^{-34}}{0.66 \times 100}=10^{-35} \mathrm{~m}
$$
