The concept used to solve this problem is based on tension in the string.
Initially, the angle made by the wire can be calculated by using the relation between sine of angle formula. Later, the radius can be calculated by equating the tension formula along vertical and horizontal axis. Finally, the tension in the upper and lower wire can be calculated by solving the tension equation.
The expression for the angle between wire and the midpoint line is,
Here, 
is the angle, 
is the distance from midpoint to one end of the wire, and
is the length of the wire.
The expression for the tension along x-direction is,
Here, 
are the tensions in the upper wire and in the lower wire respectively, 
is the mass, 
is the velocity, and
is the radius.
The expression for the radius is,
The expression for the tension along y-direction is,
Here, 
is the gravitational acceleration.
