- At an instant in time, an electron has velocity, v = 100i - 300j + 200k km/s while it is in a magnetic field, B = 2i - 3j + 4k T. Find the acceleration of the electron at this instant. Use the vector table below to show any important vectors. Show only numerical results in the table. (m = 9.109 x 10*3" kg, q = -1.6 X 10*1º C) Vector i karrow_forwardA neutral particle is at rest in a uniform magnetic field of magnitude |B|. At time t = 0 it decays into two charged particles each of mass m. a) If the charge of one of the particles in +q, what is the charge of the other? b) The two particles move off in separate paths, both of which lie in the plane perpendicular to B. At a later time the particles collide. Express the time from decay in terms of m, |B| and q.arrow_forwardA negatively charged particle (m = 5.0 g, q = -70 microC) moves horizontally at a constant speed of 30 km/s in a region where the free fall gravitational acceleration is 9.8 m/s2 downward, the electric field is 700 N/C upward, and the magnetic field is perpendicular to the velocity of the particle. a) What are the directions of the electric and magnetic forces on the particle? O Both forces are upward O Electric force downward; magnetic force upward O Both forces are downward O Electric force upward; magnetic force downward b) What is the magnitude of the magnetic field in this region?arrow_forward

The impulse of the first particle is: a) twice smaller than the second b) twice as large as the second c) equal to the momentum of the second particlearrow_forwardNear the surface of the earth, a magnet is made to levitate above another magnet, which is on a table, due only to magnetic force. The levitating magnet has a mass of 150 g with its north pole facing the magnet on the table and its south pole facing upwards. A stream of electrons is shot between the magnets, perpendicular to the field. Describe, in general, what will happen to the electrons, ignoring the effects of gravity on the electrons. Sketch the magnetic field between the two magnets.arrow_forward
