Zero
Proof: R2 = P2 + Q2 + 2 P Q cos@
Differentiating with respect to @, we get 0 = 0 + 0 + 2 P Q (-sin @)
This is because R is maximum and P and Q are not variables.
===> sin@ = 0
===> @ = 0

What is the minimum number of unequal vectors that give a zero resultant?
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.
What is the polygon law of forces?
" If a number of forces acting at a point be represented in magnitude ad direction by the sides of a polygon in order, then the resultant of all these forces may be represented in magnitude and direction by the closing side of the polygon taken in opposite order "
Statement of polygon law of forces?
if several COPLANAR FORCES are acting at a point simultaneously such that each one of them can be represented in direction and magnitude by a side of a polygon, taken in order, then the resultant is given by the closing side in the reverse order
What do you call the sum of all the forces?
The resultant.
What is the resultant of two forces 4N and 5N exerted at an angle 30 degrees between them?
using parallelogram principle. 15.5N
If two identical forces are acting on a body find the angle when resultant is maximum?
Zero degrees. This essentially adds up the forces.
When two forces P and Q acting along the same line then its resultant?
The resultant of two forces P and Q acting along the same line is the algebraic sum of the two forces. If they are acting in the same direction, the resultant is equal to the sum of the forces. If they are acting in opposite directions, the resultant is equal to the difference between the two forces.
Are resultant forces acting in different directions equal?
No, resultant forces acting in different directions are not equal. The resultant force is the net force that results from combining all the individual forces acting on an object, taking into account their direction and magnitude.
What is th resultant force between balanced force?
When there are balanced forces acting on an object, the resultant force is zero. This means that the forces are equal in magnitude and opposite in direction, resulting in no acceleration of the object.
How do we calculate resultant forces?
To calculate the resultant force, you need to add up all the individual forces acting on an object. If the forces are acting in the same direction, you simply add them up. If the forces are acting in different directions, you need to consider both the magnitude and direction of each force to determine the resultant force.
Two forces one 500 gf and the other 800gf act upon a body what are the maximum and minimum possible values of the resultant force?
The maximum resultant force occurs when the two forces are acting in the same direction, resulting in 1300 gf (500 gf + 800 gf). The minimum resultant force occurs when the two forces are acting in opposite directions, resulting in 300 gf (800 gf - 500 gf).
What is th effect on the resultant of increasing the angle between the two forces?
Increasing the angle between two forces will decrease the magnitude of the resultant force. When the angle is 180 degrees (opposite directions), the forces will cancel out, resulting in a zero resultant force. Conversely, when the angle is 0 degrees (same direction), the forces will add up, resulting in a maximum resultant force.
What is the maximum resultant possible when adding a 3N force to an 8N force?
The maximum resultant possible when adding a 3N force to an 8N force is 11N. This occurs when the two forces are acting in the same direction, resulting in additive effects on the total force magnitude.
If a book remains stationary on a table are the forces acting upon the book in equilibrium what is the resultant of the force acting upon the book?
Yes, if a book is stationary on a table, the forces acting on it are in equilibrium. The resultant force acting on the book would be zero, as the forces are balanced and there is no net force causing any acceleration or movement.
What is the maximum resultant possible when adding 3-N force to an 8-N force?
The maximum resultant possible when adding a 3-N force to an 8-N force is 11 N. This occurs when both forces are acting in the same direction.
What is the difference between perpendicular force and resultant force?
Perpendicular force is a force acting at a right angle to a surface or object, while resultant force is the single force that effectively replaces multiple forces acting on an object. Perpendicular force only affects motion in the direction it is applied, whereas resultant force takes into account all forces acting on an object to determine its overall motion.
What is a resultant?
A resultant is when a force equivelent to two or more other forces acting in different directions at the same point.AnswerA resultant is when a force equivelent to two or more other forces acting in different directions at the same point.
