Homework Statement
I'm struggling with question 6 and 7 on this exercise. I have no idea where to start so basic help would be needed to get me started.
Thanks!

AlchemistK said:Try finding the angles between the vectors, then resolve the "2g" vector using trigonometry in such a way that the vectors balance each other out.
jedishrfu said:well what is the angle of P relative to the horizontal? 40 degrees plus 90 degrees right?
studentxlol said:No good. I need full method.
jedishrfu said:sorry we can't give you the answer you have to work it out for yourself. you can show us the work and we'll tell you where you went wrong.
A balanced force is when the forces acting on an object are equal in magnitude and opposite in direction, resulting in a net force of zero. An unbalanced force is when the forces acting on an object are unequal in magnitude, resulting in a net force that causes the object to accelerate.
To determine the resultant force, you must first resolve each force into its horizontal and vertical components. Then, add all the horizontal components together and all the vertical components together. The resultant force is the vector sum of these two components.
A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction. Examples of scalar quantities in mechanics include distance, speed, and mass, while examples of vector quantities include displacement, velocity, and force.
Yes, forces can be added or subtracted using vector addition and subtraction. When adding forces, the direction and magnitude of each force must be taken into account. When subtracting forces, the direction and magnitude of the force being subtracted must be reversed.
An object is in equilibrium when the net force acting on it is zero. This can be determined by resolving all the forces acting on the object and adding them together. If the resultant force is zero, the object is in equilibrium. Additionally, an object is in equilibrium if it is at rest or moving at a constant velocity.
