4. 18 N

MCQ 18: When an object is tilted slightly and it topples over, the state is termed

1. Unstable equilibrium
2. Stable equilibrium
3. Neutral equilibrium
4. Stability

MCQ 19: In order to satisfy the Principle of Moment for an object in equilibrium, one needs to make sure that

1. Sum of horizontal forces = Sum of vertical forces = 0
2. Sum of clockwise moments about pivot > Sum of anti-clockwise moments about pivot
3. Sum of clockwise moments about pivot < Sum of anti-clockwise moments about pivot
4. Sum of clockwise moments about pivot = Sum of anti-clockwise moments about pivot
