(a)
The radiation pressure exerted by an electromagnetic wave on a surface that totally absorbs the radiation is given by
where
I is the intensity of the wave
c is the speed of light
In this problem,
and substituting , we find the radiation pressure
(b)
Since we know the cross-sectional area of the laser beam:
starting from the radiation pressure found at point (a), we can calculate the force exerted on a tritium atom:
And then, since we know the mass of the atom
we can find the acceleration, by using Newton's second law:
