High-Energy Cancer Treatment. Scientists are
working on a new technique to kill cancer cells by zapping
them
with ultrahigh-energy (in the range of 1012 W)
pulses of light that last for an extremely short time (a few
nanoseconds). These short pulses scramble the interior of a cell
without causing it to explode, as long pulses would do. We can
model a typical such cell as a disk in 4 mm diameter, with the
pulse lasting for 4 ns with an average power of 4.5
x1012 W. We shall assume that the energy is spread
uniformly over the faces of 100 cells for each pulse. How much
energy is given to the cell during this pulse?
(answer in 2 decimal places )
pi = 3.1416
muo = 4p x 10-7 T
. m/ A
c = 3 x 108 m/s
eo=
8.85 x 10-12 C2 / N m2
