Center of Mass question

2022 · 29 Jul · Shift 1 · Q53

JEE MainPhysicsCenter of MassMCQ+4 / −1
Two bodies of mass 1 kg1 \mathrm{~kg}1 kg and 3 kg3 \mathrm{~kg}3 kg have position vectors i^+2j^+k^\hat{i}+2 \hat{j}+\hat{k}i^+2j^​+k^ and −3i^−2j^+k^-3 \hat{i}-2 \hat{j}+\hat{k}−3i^−2j^​+k^ respectively. The magnitude of position vector of centre of mass of this system will be similar to the magnitude of vector :
  1. A
    i^+2j^+k^\hat{i}+2 \hat{j}+\hat{k}i^+2j^​+k^
  2. B
    −3i^−2j^+k^-3 \hat{i}-2 \hat{j}+\hat{k}−3i^−2j^​+k^
  3. C
    −2i^+2k^-2 \hat{i}+2 \hat{k}−2i^+2k^
  4. D
    2i^−j^+2k^2 \hat{i}-\hat{j}+2 \hat{k}2i^−j^​+2k^
