Explanation:
From the question we are told that
The distance of separation is
The current on the one wire is
The current on the second wire is
Generally the magnitude of the field exerted between the current carrying wire is
Here is the magnetic field due to the first wire which is mathematically represented as
Here is the distance to the half way point of the separation and the value is

Answer:
19.5°
Explanation:
The energy of the mass must be conserved. The energy is given by:
1)
where m is the mass, v is the velocity and h is the hight of the mass.
Let the height at the lowest point of the be h=0, the energy of the mass will be:
2)
The energy when the mass comes to a stop will be:
3)
Setting equations 2 and 3 equal and solving for height h will give:
4)
The angle ∅ of the string with the vertical with the mass at the highest point will be given by:
5)
where l is the lenght of the string.
Combining equations 4 and 5 and solving for ∅:
6)
