If two vectors A ⃗ \vec{A} A and B ⃗ \vec{B} B having equal magnitude R are inclined at an angle θ, then

Options

• Option A

  |$\vec{A}$- $\vec{B}$| = √2 R sin(θ/2)

• Option B

  |$\vec{A}-\vec{B}$| = 2R sin(θ/2)

• Option C

  |$\vec{A}+\vec{B}$| = 2R cos(θ/2)

• Option D

  |$\vec{A}-\vec{B}$| = 2R cos(θ/2)
