19) For 5 points of extra credit: Place a weight holder with 100 g at the 20-cm mark and a weight holder with 200 g at the 60-cm mark on the meter stick. Experimentally determine the position for a third weight holder with 50 g so that the system is in equilibrium. Follow a procedure similar to what is outlined in steps 1-18. Compute the percent difference between the upward and downward forces and compute the percent difference between the clockwise and counterclockwise torques. Show all of your work below and on the next page Here 100 g is at 20 cm, 200g is at 60 cm mark then where 50g must be for equilibrium Now from balance of force F (down) = 0.195 N +0.35 9.8= 3.625 N F(up) T 3.625 N must be for balance of force Now for balance of torque T-100 g (20.3)-200 g (9.7) + 50 g.x=0 x = 1.8 cm at right from centre hence position is 50.3 + 1.8 = 52.1 cm % diff=
