Question 7:
Two masses 40g and 60g respectively, are attached firmly to the ends of the light meter rule. The center of gravity of the system is
  • A At the mid-point of the meter rule
  • B 40cm from the lighter mass
  • C 40cm from the heavier mass
  • D 60cm from the heavier mass
  • E Indeterninate because the meter-rule is light
