Following forces start acting on a particle at rest at the origin of the co-ordinate system simultaneously F⃗1=5i^−5j^+5k^,      F2=2i^+8j^+6k^,F3=−6i^+4j^−7k^,F4=−i^−3j^−2k^.{\mathrm{\vec F}_1} = 5\hat i - 5\hat j + 5\hat k,\mathrm{\;\;\;}{\mathrm{F}_2} = 2\hat i + 8\hat j + 6\hat k,{\mathrm{F}_3} = - 6\hat i + 4\hat j - 7\hat k,{\mathrm{F}_4} = - \hat i - 3\hat j - 2\hat k. The particle will move
View answer and explanation
Correct option: B
in y-z plane
Option B (in y-z plane) is correct because the net force has no x-component, indicating movement only in the y-z plane.
