If the demonstrator pulls down, the weight will both move _____ the tube and _____ its angular velocity.1) closer to, decrease2) closer to, increase3) farther from, decrease4) farther from, increase

Answer 1

A weight is suspended from a string and spun in a circle. The string passes through a vertical tube and comes out the bottom. The demonstrator’s hand holds the string below the tube. If the demonstrator pulls down, the weight will both move closer to the tube and increase its angular velocity.

Hence, the correct option is (2)
