Given four forces : `vec F_1 = 3 hat i - hat j + 9 hat k` `vec F_2 = 2 hat i - 2 hat j + 16 hat k` `vec F_3 = 9 hat i + hat j + 18 hat k` `vec F_4= hat i + 2 hat j - 18 hat k` If all these forces act on a particle at rest at the origin of a coordinate system, then identify the plane in which the particle would begin to move ?
