Answer:
The magnitude of magnetic field at given point =  ×
 ×  T
 T
Explanation:
Given : 
Current passing through both wires = 5.0 A
Separation between both wires = 8.0 cm
We have to find magnetic field at a point which is 5 cm from any of wires.
From biot savert law, 
We know the magnetic field due to long parallel wires.
⇒ 
Where  magnetic field due to long wires,
 magnetic field due to long wires,  
  ,
,  perpendicular distance from wire to given point
 perpendicular distance from wire to given point
From any one wire  5 cm,
 5 cm,  3 cm
 3 cm
so we write,
∴ 
  
  ![B =\frac{ 4\pi \times10^{-7} \times5}{2\pi } [\frac{1}{0.03} + \frac{1}{0.05} ]](https://tex.z-dn.net/?f=B%20%3D%5Cfrac%7B%204%5Cpi%20%5Ctimes10%5E%7B-7%7D%20%5Ctimes5%7D%7B2%5Cpi%20%7D%20%5B%5Cfrac%7B1%7D%7B0.03%7D%20%2B%20%5Cfrac%7B1%7D%7B0.05%7D%20%5D)
  
Therefore, the magnitude of magnetic field at given point =

Answer:
Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.
