Question

) there are two poles of equal height 15mts. one cable with length 16mts is hanging between that two poles. the height from center of the cable to earth is 7mts then what is the distance between that two poles?

Answer 1

The distance between the poles is zero.

Reason :

If the cable is hanging 7 meters above the ground its center will be :
15 - 7 = 8 mts

This is its radius.

It's diameter equals its length.

Hence the distance between the poles is zero.
