A rod of length L and mass M fixed at the origin at one end is placed along the x-axis at t = 0. It starts rotating about the z-axis in the x-y plane anti-clockwise as seen from the positive z-axis due to a force F always perpendicular to the rod acting at the free end. The angular velocity of the rod at time t is
1
\(\frac { Ft }{ML } \)
2
\(\frac { 2Ft }{ML } \)
3
\(\frac { 3Ft }{ML } \)
4
\(\frac { 4Ft }{ML } \)
