Question # 3
Which of the objects is in neutral equilibrium?
When an object is in neutral equilibrium, its center of gravity stays at the same level if it is pushed or pulled.
Question # 4

Question # 8
Two forces 12 N and 5 N are added together by head to tail rule such that force of 12 N is taken as first force and 5 N is taken as second force. The resultant force has magnitude of 13 N. If we take 5 N as first force and 12 N as second force and add them by head to tail rule then what will be the magnitude of resultant force?

Question # 12
Which of the objects in the figure represents unstable equilibrium?
Question # 13
Two equal and opposite forces are acting on an object at different points. The first condition of equilibrium is satisfied but the object is not in equilibrium. What is the action of these forces then?
In given case Σ F = 0 , but still the body is not in complete equilibrium!
Question # 14
Question # 15

Question # 20
What will be the tension in the string when a block of 200 N weight is supported by that string?
Weight of block is acting downwards. In order to prevent block from falling, the string must provide equal and opposite force.
Question # 21
