Answer:
When the coins are placed 12 cm away from the end P, the centre of mass gets shifted by 5 cm from point R toward the end P. The centre of mass is located at a distance of 45 cm from point P. The net torque will be conserved for rotational equilibrium about point R. Hence, the mass of the metre stick is 66 g.
