A block of mass 0.4 kg is attached to a cord of

A block of mass 0.4 kg is attached to a cord of length 0.2 m. which is fixed at one end. The block moves in a horizontal circle on a frictionless table. A second block of mass 0.4 kg is attached to the first by a cord of length 0.2 m and also moves in a circle, as shown in the Figure. If the period of the motion is 0.8 s, calculate the tension in the outer cord. (Your result must contain 1 digits after the decimal and 2% of error will be tolerated in your answers. Take g-9.81 m/s2.)
