JEE MainPhysicsLaws of MotionMCQ+4 / −1
A body of mass 4 kg4 \mathrm{~kg}4 kg experiences two forces F⃗1=5i^+8j^+7k^\vec{F}_1=5 \hat{i}+8 \hat{j}+7 \hat{k}F1​=5i^+8j^​+7k^ and F→2=3i^−4j^−3k^\overrightarrow{\mathrm{F}}_2=3 \hat{i}-4 \hat{j}-3 \hat{k}F2​=3i^−4j^​−3k^. The acceleration acting on the body is :
  1. A
    2i^+j^+k^2 \hat{i}+\hat{j}+\hat{k}2i^+j^​+k^
  2. B
    4i^+2j^+2k^4 \hat{i}+2 \hat{j}+2 \hat{k}4i^+2j^​+2k^
