Question

What is the difference between magnitude of vector R and resultant of 2 different vectors R->

Answer 1

A resultant vector is the combination of two or more single vectors. When used alone, the term vector refers to a graphical representation of the magnitude and direction of a physical entity like force, velocity, or acceleration.velocity, in Physics, must be expressed as a vector with both a magnitude and a direction. For instance, 5 m/s Eastward is a velocity because it tells you the magnitude of the movement, 5 meters per second, as well as the direction which is Eastward.

A resultant vector is the combination of two or more single vectors. When used alone, the term vector refers to a graphical representation of the magnitude and direction of a physical entity like force, velocity, or acceleration.To find the resultant vector, we should perform arithmetic operations such as addition,subtraction.
For parallelogram, use pythagorous theorem
