A 70 kg tightrope walker is the exact middle of a span of her rope. At that point each rope makes an angle of 3 degrees below horizontal with its supporting column. What is the TENSION in the ropes.

The tension is      

Explanation:

From the question we are told that

   The  mass of the tightrope  walker is  m =  70 kg

    The angle of the rope with the horizontal is  

Generally the net force on the vertical axis at  equilibrium is mathematically represented as

=>    

=>        

=>        

=>
