Question
4.00 kg block is attached
to a vertical rod by means
of two strings. When the system
rotates about the axis of the rod,
the strings are extended as shown
in Fig. and the tension
in the upper string is 80.0 N. (a)
What is the tension in the lower
cord? (b) How many revolutions
per minute does the system make?
(c) Find the number of revolutions
per minute at which the lower
cord just goes slack. (d) Explain
what happens if the number of
revolutions per minute is less than
that in part (c).
