Question # 6
A man is pulling a cart with a force of 120 N making 45 o angle with the ground. Calculate the x-component of the force which actually causes the cart to move?
Question # 7
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?

If two forces of 16 N towards north and 10 N towards south are acting on an object. What will be resultant force?
Question # 12
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 # 13
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 # 14
When a body is in stable equilibrium, its centre of gravity is at the
