WebPractice set 1: Magnitude from components. To find the magnitude of a vector from its components, we take the square root of the sum of the components' squares (this is a direct result of the Pythagorean theorem): For example, the magnitude of (3,4) (3,4) is \sqrt {3^2+4^2}=\sqrt {25}=5 32 +42 = 25 = 5. WebJul 18, 2024 · Answer: Magnitude cannot be negative. It is the length of the vector which does not have a direction (positive or negative). The zero vector (vector where all values are 0) has a magnitude of 0, but all other vectors have a positive magnitude. Is the magnitude of a vector quantity always positive?

WebMar 18, 2024 · Equality of vectors Two vectors are equal if they have the same magnitude and the same direction.
