Given vectors A→=3i^+2j^−4k^ and B→=−2i^+3j^+5k^, find the vector A→−B→.
= 5\hat{i} - \hat{j} - 9\hat{k}
Step 1 :The subtraction of two vectors is done component-wise. Thus, the difference A→−B→ can be calculated as follows:
Step 2 :A→−B→=(3i^+2j^−4k^)−(−2i^+3j^+5k^)
Step 3 := (3 - (-2))\hat{i} + (2 - 3)\hat{j} + (-4 - 5)\hat{k}
Step 4 := 5\hat{i} - \hat{j} - 9\hat{k}
