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.
That would be 13N and 3N.
The dot product of force and velocity is equal to
If two forces are in the same direction, then their resultant is also in the same direction, and its magnitude is the sum of the two components' magnitudes.
The maximum resultant occurs when the forces act in the same direction. Its magnitude is 15 N.
They have equal magnitudes and opposite directions.
Zero. Forces combine as vectors. The magnitude of the resultant force is equal to the sum of the magnitudes of the two combining forces only when the forces are parallel. Caveat: This does assume that the "maximum result" desired is a single force, such as would be relevant in producing the linear acceleration of a mass. If, for instance, one wanted to produce the maximum torque as a "result," the points (locations) where the forces were applied would make a difference and there are circumstances where torque would be maximized by oppositely directed forces.
-- When forces of unequal magnitude are added, the magnitude of the sum can be anything between the difference and sum of the individual magnitudes, depending on the angle between them. -- When forces of equal magnitude are added, the magnitude of the sum can be anything between zero and double the individual magnitudes, depending on the angle between them.
The magnitude of the resultant of two like parallel forces is the sum of the magnitudes of the forces and its direction will be same as the direction of the parallel forces.
If two forces are in the same direction, then their resultant is also in the same direction, and its magnitude is the sum of the two components' magnitudes.
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.

Zero degrees. This essentially adds up the forces.
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
If the opposing forces are pulling exactly opposite of each other, then take the difference of the magnitudes of the two forces (subtract the smaller value from the larger value), and the direction vector of the resultant force is in the same direction as the larger force.
ABCD is a squre. forces of magnitudes 1,2,3,P, and Q units act along AB, BC, CD, DA and AC respectively. find the value of P and Q so that the resultant of five forces is a couple
10N if both forces are in the same direction.
