Question

A proton is fired from far away toward the nucleus of an iron atom. Iron is element number 26, and the diameter of the nucleus is 9.0 fm.

What initial speed does the proton need to just reach the surface of the nucleus? Assume the nucleus remains at rest.

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

1/2 m v2 = k q1q2/r

0.5x (1.67x10-27) v2 = 9x109 (1.6x-19) (26x1.6x10-19) / 4.5fm
here diameter is 9fm ; radius =4.5fm or 8.2296 meters

0.8x10-27 x v2 =(9x109 (1.6x-19) (26x1.6x10-19) / 8.2296)

v2=7.279x10-28 / 0.8x10-28

v= sqrt(9.0989) =3.016 m/sec
