Question

tell me answer.....​

Answer 1

Answer:

0 m apart.

Explanation:

If the cable is 80 m, then half of it is 40 m. But notice 40 m from the top of a 50 m pole is already 10 m above the ground. The cable therefore is hanging directly downward. The cable has to be doubled back upon itself, and the two poles must be coincident and 0 m apart!

This part is actually a trick question: the two poles are a distance of 0 apart. No physics was required to solve this one, just logical thinking.
