Question

A heavy mass is attached to a thin wire and is whirled in a vertical circle. The wire is most likely to break

  1. When the mass is at the highest point of the circle    
  2. When the mass is the lowest point of the circle    
  3. When the wire is horizontal    
  4. At an angle of cos to the power of negative 1 end exponent invisible function application open parentheses 1 divided by 3 close parentheses from the upward vertical    

The correct answer is: When the mass is the lowest point of the circle


    Because here tension is maximum
