Q1. A small 0.532 kg object moves on the frictionless horizontal table in a circular path of radius 1.33 m. The angular speed is 6.20 rad/s. The object is attached to the string of negligible mass that passes through a small hole in the table at the center of circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will tolerate a tension of no more than 108 N, what is the radius of the smallest possible circle on which object can move?

Q2. Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. The length of each rod is 0.90m, and the mass of each is 0.078 kg. One rod is held in place above the ground, while other floats beneath it at a distance of 8.2 x 10-3 m. find out the current in the rods.
