Solution to Brilliant Physics Problem "Eureka"

Main post link -> https://brilliant.org/physics-problem/eureka/?group=skqQUh8aEBhb

Dear users and administrators, I would like to refer to the question state above. Apparently the solution to the exact same question in level 3 and level 5 is different. My friend has also received a notification that there are some errors in this problem? Will the challenge masters kindly enlighten on why this is so?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Also I think there errors, also think there should be the value of emissivity of the lamp !

Totally agreed. And now my friends are getting it correct when we keyed in the same thing.

There was a typo in the problem answer. It's being fixed and all points will be appropriately assigned shortly.
