Here’s How to Crack It
Place the tail of B at the tip of A and connect them:
Scalar Multiplication of Vectors
A vector can be multiplied by a scalar (that is, by a regular number), which results
in a vector. Scalars scale a vector in the sense that they alter the magnitude but not
the direction. If the original vector is A and the scalar is 4, then the scalar multiple
is 4A. Simply put, it has a magnitude that is four times greater than the original
vector. The vector −4A would also be four times greater than A, but would point in
the opposite direction.
magnitude of kA = |k|× (magnitude of A)
