To subtract a vector, B, from vector A Draw the first vector A. Draw the second vector B. Draw the negative of the second vector, -B. A negative vector has the same magnitude as the original vector, but points in the opposite direction. Now slide the second vector -B, so that its tail is at the head of the first vector. The subtraction of vector B from A is a vector drawn from the tail of the first vector, A, to the head of the second vector, -B. What is the resultant of A - B, where A = 10 km, North and B = 5 km, West? R R R (A) (B) (C) R (D)
