Finger need to be placed to balance the meter stick

Reference no: EM13544807

You would like to balance a meter stick on your finger. The meter stick has a mass of m = 0.2 kg. (a) How far from the end should you place your finger to balance the stick? (b) Suppose two additional masses of M = 0.1 kg are placed at the positions x = 0 cm and x = 70 cm. Now where does your finger need to be placed to balance the meter stick?
