A force `barF=barVxxbarA` is exerted on a particle in addition to the force of gravity, where `barV` is the velocity of the particle and `barA` is a constant vector in the horizontal direction. The minimum speed of a particle of mass 3kg be projected, so that it continues to move undeflected with a constant velocity is `(xg)/A.` Then 'x' is (consider the plane of the ground as xy plane)
