Two masses 
and 
are connected at the two ends of a massless rigid rod of length 
. The road is suspended by a thin wire of torsional constant k at the centre of mass of the rod-mass system (see figure). Because of torsional constant k, the restoring torque is 
for angular displacement 
. If the rod is rota ted by 
and released, the tension in it when it passes through its mean position will be:
A
B
C
D
