Energy of gamma rays is given by equation

here we know that
h = Planck's constant

now energy is given as


now by above equation



now for wavelength we can say



Answer:
<h2>135,000 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 900 × 150
We have the final answer as
<h3>135,000 J</h3>
Hope this helps you
