A mass m is attached to a thin wire and whirled in a vertical circle . The wire is most likely to break when :
The mass is at the highest point
the wire is horizontal
The mass is at the lowest point
Inclined at an angle of 60 degree from vertical
The resultant of weight and centrifugal force is maximum at bottom . so wire is mostly like to break at bottom
The mass is at the highest point
Option 2)the wire is horizontal
Option 3)The mass is at the lowest point
Option 4)Inclined at an angle of 60 degree from vertical
