Following forces start acting on a particle at rest at the origin of the coordinate system simultaneou `vecF_(1)=5hati-5hatj, vecF_(2)=2hati, 8hatj+6hatk, vecF_(3)+4hatj-7hatk, vecF_(4),=-hati-3hatj-2hatk`. The particle will move

Options

A. in x-y plane
B. in y-z plane
C. in x-z plane
D. along x-axis

Answer

B

Explanation

`F_(1)+F_(2)+F_(3)+F_(4)=4hatj+2hatk`
his force is in y-z plane. Therefore the particle moves in y-z plane
