An electron moving with a velocity, v =(4.0 i+ 3.0 j+ 2.0k) x 10^6m/s enters a region where there is a uniform electric field and a uniform magnetic field. The magnetic field is given by B =(1.0 i − 2.0 j + 4.0k) x 10^−2T. If the electron travels through a region without being deflected, what is the electric field?

A loop of wire has the shape shown in the drawing. The top part of the wire is bent into a semicircle of radius r = 0.27 m. The normal to the plane of the loop is parallel to a constant magnetic field (φ = 0˚) of magnitude 0.87 T. What is the change ΔΦ in the magnetic flux that passes through the loop when, starting with the position shown in the drawing, the semicircle is rotated through half a revolution?
