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.
What is th resultant force between balanced force?
"Balanced forces" means that the sum of all forces acting on an object - i.e., the resultant force - is equal to zero.
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?
All of the forces together balance out. The resultant of the forces is therefore nil. That applies to all equilibrium.
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.
What is d'alembert's principle?
the principle that resultant of the external forces and kinetic reaction acting forces is zero
What is sum of the forces that are acting on an object?
Net Force, Or Net Resultant Force, or Resultant force
Two types of unbalanced forces and what a balanced force is?
If the resultant of all the forces acting on a body is zero, the forces are called balanced forces. 2 types of unbalanced forces are naet force and resultant force.
What term to the sum of all of the forces acting an object?
resultant or net force
What is determined by combining forces?
this is the net resultant force acting on the object, taking into account all of the forces acting, their strength and direction.
What is the difference between perpendicular force and resultant force?
Perpendicular force means they act at right angles to each other, while the resultant is the summation of all the forces acting. The determination of the resultant force often needs vector calculus .
What is the maximum net force possible of two forces with a magnitude of 25N and 15N?
Depending on the angle between them, those two forces can combine to producea resultant anywhere between 10N and 40N. The maximum of 40N occurs whenboth forces act in exactly the same direction.
What terms refer to the sum of all the forces acting an object?
resultant or net force
