Three. Equal forces, two.
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
the opposite to vector addition is vector subtraction.
prrpendicular projections of a vector called component of vector
The unit vector is a vector whose magnitude is 1.

The definition of unbalanced force is a force that together can equal a certain number and will make a change of the objects motion. or an unequal balance of forces on an object
If the forces are balanced, that means they cancel out one another - their vector sum is zero. This can't happen with two forces of unequal magnitude (strength), but it is possible to have three or more forces of unequal magnitude cancel one another; for example (in a one-dimensional example), forces of 3, -2, and -1.
Two vectors; V1 + V2=0 where V1= -V2, two opposite vectors.
Two is the minimum number of vectors that will sum to zero.
-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.
In that case, the forces are said to be unbalanced.
The sum of two unequal vectors can not be zero, because we can get minimum magnitude of two vectors when they are in opposite direction and can only get zero magnitude when they are equal in magnitude.................................... Answered by: SAJJAD AHMED(bfps doha Qatar)
Forces acting on a point such that it gives a null vector by vector addition law, then such type of forces are called balanced forces.
There is no such thing as scalar and vector forces. However, there are scalar and vector QUANTITIES, and force is a vector quantity, as all forces have direction and magnitude. Scalar quantities, on the other hand, have only magnitude and no direction.
The vector sum of a group of forces is zero. The vector sum of a group of forces isn't zero.
Force is a vector, and so the sum of all forces acting on an object is a vector sum.
