The magnetic field strength is  
Explanation:
From the question we are told that 
              The  length line   above the ground  is  
               The current of the line is  
               The voltage of the line is 
Generally magnetic field strength is mathematically represented as 
               
Where   is the permeability of free space
 is the permeability of free space  
              
                 ![= (2.0*10^{-7})[\frac{200}{20} ]](https://tex.z-dn.net/?f=%3D%20%282.0%2A10%5E%7B-7%7D%29%5B%5Cfrac%7B200%7D%7B20%7D%20%5D)
                
               
Earths magnetic field is approximately given as 
    So the percentage would be

Answer:
KE = 1.05 x105 Joules
Explanation:
KE = 4 * (1.04653 x 105 J) = 4.19 x 105 Joules.
