Cable is 80 m long
50 m
50 m
| 10 m​

Answer 1

Answer:

$\huge{ \mathbb{ \pink{HEYA \: \: FOLKS!!}}}$

Equation of catenary is y=cosh(X/a)

In our problem a=10m . so we calculate X for y=50m

Then y/a=cosh(X/a). (OR)

50/10=5=cosh(X/10)

Now from the tables of hyperbolic cosine function,

x/10=2.3 (OR)

x/10=2.3 (OR)

x=23

Hence distance between two poles is 46m.
