Explanation:
The above condition can be explained with the reference from Electricity chapter.
It is dependent on the potential of a system.
Clearly, the cage is a type of conductor.
Now, we know that, charges reside only on the surface of a conductor.
Inside the conductor, charge is zero.
So, even if the metallic cage was charged up with the help of powerful electric machine, the charges resided on the surface.
Thus, Pluto was safe.
