One of them is negative or both of them are zero,
No. At least, if you consider the standard vectors in Rn space, often used in physics, their length (or magnitude) must always be greater than or equal to any of its components.
All components cancel. The component vector sum is zero. example: x-components: A<-------- -------->B = zero same for y-components
No. The magnitude of a vector can't be less than either of its components.
yes. specially when the components have same length but in different direction
Can a magnitude of vector be smaller than magnitude of any of its component
All components of the zero vector equal to zero.
Correct.
zero
All Components cancel The Component vector sum is zero Example: x-components A<------------------->B = zero same for y-components
Zero
Yes. A vector in two dimensions is broken into two components, a vector in three dimensions broken into three components, etc... If the value of all but one component of a vector equal zero then the magnitude of the vector is equal to the non-zero component.
Zero plus one equals one.
Negative five.
Zero (0)
yes
4 + 0 = 4
-4 plus 4 equals zero.
