A beam of alpha paricles is incident on ...

A beam of alpha paricles is incident on a target of lead. A particular alpha paticles comes in 'head- on' to a particular lead nucleus and stops `6.50 xx 10^(-14)` m away from the center of the nucleus. (This point is well outside the nucleus.) Assume that the lead nucleus, which has `82` protons, remains at rest. The mass of alpha particle is `6.64 xx 10^(-27)kg`
What was the initial speed of the alpha particle?

A

`132 xx 10^(2) m//s`

B

`1.32 xx 10^(2) m//s`

C

`13.2 xx 10^(2) m//s`

D

`0.13 xx 10^(2) m//s`
