A block of mass 2.0 kg is attached to a rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended to a length 1.0m and the upper string has a tension of 30.N. The strings make an angle of 30 with rod.

A) What is the tension in the lower string Tl ?

B) How many revolutions per sec does the system make?

C) If the lower string is cut, what is the value of the new Tu? And what is the number of revolutions per sec?
