black hole question...?

Question

Take two identical, nonrotating, 5-solar-mass black holes and place them side by side. Add one solar mass of pineapples to the left-hand one and one solar mass of radioactive uranium to the right-hand one (without changing their electric charge or their rotation). Afterward, how do these two black holes differ?

a. The left-hand one will smell better.
b. The right-hand one is radioactive, emitting alpha particles, electrons, and gamma rays.
c. The right-hand one has a stronger gravitational field because of the denser matter inside it.
d. They do not differ at all.

Answer 1

It takes infinite time for objects falling into a black hole to dissappear into the event horizon. Therefore one of the black holes will emit radiation, but at an ever decreasing rate since the event horizon will steal more and more of the energy of the escaping radiation. The radiation will also be more and more red-shifted, so that the gamma rays will eventually become x-rays, then visible light, then infrared, etc. So the answer is b tending toward d. The pineapples would probably also release a lot of radiation as they're being torn appart near the event horizon, so the b answer is streaching the point pretty thin.

Answer 2

Answer C is closest to being correct theoreticaly.

However, as matters stand today, the entire concept of
Black Holes is just that...Theory. So, to be truthful with you,
all of this is conjecture and hypothesis. I do not think that one
could obtain one solar mass of uranium in any event, or even
begin to accumulate one solar mass of pineapples. Beyond
the accumulation and delivery problems one would encounter
in so large a task, there happens to be a problem with satisfactory storage of the materials during the accumulation process. Surely you can see that the workers, however many billions of them there might be (a solar mass quantity is rather large), would be sickened and die from radiation poisoning well before accomplishment of the task. As a side issue, since the solar mass quantity of pineapples might well occupy a space in excess of 109 times the diameter of Earth, pineapple growers would have to accumulate all the pineapples grown everywhere in the universe for billions of years to reach the desired stocking level of one solar mass
before delivery to the Black Hole.

A minor incidental problem was forwarded to me by the Secretary of Intergalactic Transportation. He just reported
to me that there might be some delays in transporting the stocks from our warehouses to the Black Hole due to a
reported problem in return flights of the transporter space
craft. Apparently none of the transporters will ever return
for second and third shipments due to the unforseen gravitational pull of the destination holes themselves. Our
transporters have never been heard from again. In essence he is suggesting that we will require a massive manufacturing program to construct 477 Quadrazillion Jumbo transporters to deliver the materials.

The International Society of Accounting has also been in contact with me raising cane about the lack of availability of live customers at the receiving end of our supply chain to sign receipts for the delivered goods. In essence he says that we will have no record of progress made in filling the orders.
