Aparticle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, a velocity v⃗ =(3.00×104m/s)j^. what are the magnitude and direction of the particle’s acceleration produced by a uniform magnetic field b⃗ =(1.63t)i^+(0.980t)j^?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
