Parallel vectorsEasyQuestion 260005

Question

Vectors a⃗ = 2î + 4ĵ and b⃗ = î + 2ĵ are:
  1. A
    Parallel
    Correct
  2. B
    Perpendicular
  3. C
    Anti-parallel
  4. D
    Neither

Correct answer

Parallel

Explanation

b⃗ = (1/2)a⃗. When one vector is a scalar multiple of another, they are parallel (or anti-parallel if the scalar is negative). Here the scalar 1/2 > 0, so they are parallel.
