A charged particle of mass 2 kg and 1 C starts at the origin with velocity 3 m/s and travels in a region of uniform magnetic field B = 10 Wb/m. At t = 4 s, do the following:
a) Calculate the velocity and acceleration of the particle.
b) Calculate the magnetic force on it.
c) Determine its kinetic energy and location.
d) Find the particle's trajectory by eliminating t.
e) Show that its kinetic energy remains constant.
