STANDARD Physics Displacement Vectors MCQ Question

Type: MCQ-numerical-Easy

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 from A to B is

A

−2î + 4ĵ + 2k̂

B

2î − 4ĵ + 2k̂

C

2î + 4ĵ − 2k̂

D

−2î − 4ĵ − 2k̂

Correct Answer

Option A

Detailed Explanation

The displacement vector from A to B is calculated by subtracting the coordinates of A from B: r = rB - rA = (−2î + 8ĵ − 4k̂) − (0î + 4ĵ − 2k̂) = −2î + 4ĵ + 2k̂.
