A force `vecF=vecvxxvecA` is exerted on a particle in addition to the force of gravity, where `vecv` is the veocity of the particle and `vecA` is a constant vector in the horizontal direction. With what minimum speed a particle of mass m be projected so that it continues to move undeflected with a constant velocity?

Assuming the gravity to be in negative z-direction, a force F=vxxA is exerted on a particle in addition to the force of gravity where v is the velocity of the particle and A is a constant vector in positive x-direction. With what minimum speed a particle of mass m be projected so that it continues to move undeflected with constant velocity ?

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)
