A string of length L is fixed at one end and carries a mass of M at the other end. The mass makes ( 3 ) rotations per second about the vertical axis passing through end of the string as shown. The tension in the string is ML.

Correct answer

36

Step-by-step solution

aligned & = 3 2 =6 rad / s & R=L aligned and T=M g^2+ ^4 R^2 Also, T =M ^2 L aligned & T=M(36) L & T=36 ML aligned
