question #6
reference q.46810
how do we draw the subtraction of two vectors?

Explanation:

Question #4

To draw the addition of two vectors using the head - to - tail rule, first draw the first vector. Then, place the tail of the second vector at the head of the first vector. The resultant vector is drawn from the tail of the first vector to the head of the second vector.

To measure the resultant of vector addition (from the head - to - tail diagram), we can use a ruler to measure the length of the resultant vector (which gives the magnitude if we know the scale) and a protractor to measure the angle it makes with a reference axis (to determine the direction).

To draw the subtraction of two vectors (\(\vec{A}-\vec{B}\)), we first rewrite it as \(\vec{A}+(-\vec{B})\). Then, using the head - to - tail rule, draw \(\vec{A}\) and then draw \(-\vec{B}\) (a vector with the same magnitude as \(\vec{B}\) but opposite direction) with its tail at the head of \(\vec{A}\). The resultant is drawn from the tail of \(\vec{A}\) to the head of \(-\vec{B}\).

Answer:

To add two vectors (head - to - tail rule), draw the first vector, place the tail of the second vector at the first vector's head, and draw the resultant from the first vector's tail to the second vector's head.
