With what velocity should an \( \alpha \)-particle travel towards the nucleus of copper atoms so as to arrive at a distance \( 10^{-12} \mathrm{~m} \) from the nucleus of the copper atom? \( \left(4.8 \times \sqrt{29 \times 60}=200, N_{\mathrm{A}}=6 \times 10^{23}\right. \), \( \left.e=1.6 \times 10^{-19} \mathrm{C}\right) \)
(a) \( 2 \times 10^{3} \mathrm{~ms}^{-1} \)
(b) \( 2 \times 10^{6} \mathrm{~ms}^{-1} \)
(c) \( 2 \times 10^{5} \mathrm{~ms}^{-1} \)
(d) \( 2 \times 10^{7} \mathrm{~ms}^{-1} \)
