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^?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
