Question # 1
The vertical component of force is 45 N and the angle of force with x-axis is 45o. Calculate the magnitude of force.
Use equation F y = F s i n θ
Question # 2
The horizontal component of a force is 48 N and the angle formed by the resultant force is 30o with x-axis. What will be the magnitude of force?
Question # 3
A man is pulling a cart with a force of 120 N making 45o angle with the ground. Calculate the x-component of the force which actually causes the cart to move?
Question # 4
A boy pushes a block with a force of 3 N from right to left. An other boy pushes that block with a force of 4 N at the same time from front. What will be the magnitude of the resultant force?
Question # 5
Which of the objects in the figure is in maximum stable equilibrium?
Question # 6
A boy pushes a table with a force of 7 N to the right. An other boy pushes the table at same time from the same side with a force of 8 N to the right. What will be the resultant force on the table?
Question # 7
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?
Question # 8
The horizontal component of force is 54 N and vertical component is 62 N. Calculate the angle that the resultant force makes with x-axis.
Question # 9
Which of the objects in the figure represents unstable equilibrium?
Question # 10
A 16 mg spider is hanging by a thread. It is blown sideway by the wind. What will be the total force on the spider?
Question # 11
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
What will be the tension in the string when a block of 200 N weight is supported by that string?
Question # 13
What is the vertical component of a force of 100 N acting on a body at an angle of 60o with x-axis?
Resolve vector into its components.
Question # 14
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?
