The `(x, y, z)` coordinates of two points A and B are given respectively as `(0, 4, -2) and (-2, 8, -4)`. The displacement vector form A to B isA. `-2hati + 4hatj - 2hatk`B. `2hati - 4hatj + 2hatk`C. `2hati+4hatj-2hatk`D. `-2hati-4hatj - 2hatk` |
Answer» Correct Answer - A Here, `vecr_(A) = 0hati + 4hatj -2hatk, vecr_(B) = -2hati + 8hatj -4hatk` Displacement vector from A to B is given by `vecr = vecr_(B) - vecr_(A) = (-2hati + 8hatj -4hatk)-(0hati + 4hatj -2hatk) = -2hati +4hatj -2hatk` |
