The maximum resultant occurs when the forces act in the same direction. Its magnitude is 15 N.

-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.

the largest possible resultant is if the two displacements are in the same direction, so resultant = 7 m (3+4=7) the minimum resultant is if they are in opposite directions, so minimum is 4-3= 1 m :D

3N

maximum resultant: 45 = a + b minimum resultant: 5 = a - b Solve for a in the first equation then substitute it into the second equation: a = 45 - b 5 = 45 - b -b 5 - 45 = -2b -40 = -2b 20 = b Since we know the value for b we can substitute it into the first equation to find the value for a: 45 = a + 20 45 - 20 = a 25 = a So the magnitude of each of these forces are 20N, 25N.

There is no minimum.

The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.

Zero is.

-- The minimum magnitude that can result from the combination of two vectors is the difference between their magnitudes. If their magnitudes are different, then they can't combine to produce zero. -- But three or more vectors with different magnitudes can combine to produce a zero magnitude.

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.

One.One.

the largest possible resultant is if the two displacements are in the same direction, so resultant = 7 m (3+4=7) the minimum resultant is if they are in opposite directions, so minimum is 4-3= 1 m :D

Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.

If the act together (in the same direction), the resultant force is the sum - 1300 gf (whatever that abbreviation means!). This is the maximum. If they act in opposite directions, the resultant force is the difference, 300 gf - and this is the minimum.
