Problem

Use the in-text table 'Ranges of charged particles in water', which gives a range of

4.4\,\mathrm{mm}

for a

1\,\mathrm{MeV}

electron and about

16\,\mathrm{cm}

for a

150\,\mathrm{MeV}

proton, both in water. ((a)) State the two ranges in the same unit. ((b)) How many times further does the

150\,\mathrm{MeV}

proton travel in water than the

1\,\mathrm{MeV}

electron?
