Problem 25P
(Ill) How much voltage must be used to accelerate a proton (radius 1.2 X 10-15 m) so that it has sufficient energy to just ‘‘touch" a silicon nucleus? A silicon nucleus has a charge of +14e. and its radius is about 3.6 X 10-15 m. Assume the potential is that for point charges.

ANSWER:
Step-by-step solution
Step 1 of 2
qp=+e=1,6x10-19C (the charge of the proton)
qs=+14e=14x1,6x10-19C (the charge of the silicon nucleolus)
rp=1,2x10-15m (the radius of the electron)
Rs=3,6x10-15m (the radius of the silicon nucleolus)
A proton is accelerated from point A to B in a potential difference of U. Its kinetic energy increases from KEA=0 to KEB.
