Question

If Vector A is (3,4) unit then show that the value of its unit vector is 1

Answer 1

4 - 3 =1. 4 ✖ 3 = -12

I think this would be the answer of these question

Answer 2

Explanation:

They are in opposite directions as 4−3=1

Hence dot product will be product of their magnitudes multiplied by cosθ which is -1 in this case. This gives dot product =−4×3=−12
