Q70 / 160 · AP EAMCET 2025 (23 MAY SHIFT 2) · Mathematics

If $\bar{a}=2 \bar{i}-3 \bar{j}+5 \bar{k}$ and $\bar{b}=-\bar{i}+3 \bar{j}+3 \bar{k}$ are two vectors, then the vector of magnitude 28 units in the direction of the vector $\bar{a}-\bar{b}$ is

  • A
    $3 \overline{\mathrm{i}}+6 \overline{\mathrm{j}}-2 \overline{\mathrm{k}}$
  • Correct answer
    B
    $12 \overline{\mathrm{i}}-24 \overline{\mathrm{j}}+8 \overline{\mathrm{k}}$
  • C
    $3 \overline{\mathrm{i}}-6 \overline{\mathrm{j}}-2 \overline{\mathrm{k}}$
  • D
    $12 \overline{\mathrm{i}}+24 \overline{\mathrm{j}}-8 \overline{\mathrm{k}}$

Hence, the correct answer is option: 'B'.
