Find magnetic field vector at same point in space-instant : An electromagnetic plane wave is traveling through a vacuum along the positive z-axis. At a particular point in space at one instant in time the electric field vector is E=i(6V/m) + j(6 V/m). (a) Find the magnetic field vector at the same point in sp..

Block on frictionless horizontal surface-pulling the cord : A small block on a frictionless horizontal surface has a mass of 2.25×10?2kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1) .) The block is originally revolving at a distance of 0.255m from..
