Problem
A physical balance has equal arm lengths of 30 cm each. An unknown mass is placed in the left pan. To obtain equilibrium, standard masses of 200 g are placed in the right pan along with a 5 g rider positioned 15 cm from the central knife-edge on the right arm toward the weights. Determine the mass of the unknown object.
