Two masses m and 
are connected at the two ends of a massless rigid rod of length ll. The rod is suspended by a thin wire of torsional constant k at the centre of mass of the rod-mass system (sec figure). Because of torsional constant k, the restoring torque is 
=k
for angular displacement 0. If the rod is rotated by 
0 and released, the tension in it when it passes through its mean position will be:
