I used a yard stick that is 36 inches long and has two hooks at the end to hang masses. I first found its center of gravity by balancing it on a bottle top. I was able to balance the yardstick at a distance of 18 inches from both the ends. So 18 inches point in the yardstick is its center of gravity where an object is perfectly balanced Now I hung 50 grams mass on one end and 20 grams mass on another end of the yardstick. I try to balance it at 18 inches point which was the center of gravity before. However, I cannot balance it at this point anymore since the center of gravity has changed after hanging the masses. 5. On which side do you think the center of gravity shifted? Is the new center of gravity closer to the heavy mass or it is closer to the light mass? 6. Why did the center of gravity change? (Frame your answer in terms of relation between torque and center of gravity) I used a yard stick that is 36 inches long and has two hooks at the end to hang masses.
