A conical pendulum can be constructed by attaching one end of a string to some type of overhead support such as a door frame, ceiling, or other support. Then the other end of the string is attached to a reasonably dense object that will not be extensively impacted by air resistance. Set the object into circular motion by giving it a push tangent to the circle to establish horizontal circular motion. This may take a few practice runs to perfect.

mass is 1kg, velocity is 2 m/s, length is 3 m, angle is 20*

The horizontal force (F) measured with the spring scale is equal in magnitude to the horizontal component of the tension (T_x) in the string. When the conical pendulum is set into circular motion with the same angle (20*), though F is no longer present, the value of T_x will be the same. Record the value of T_x.
