A wire curved into a 1/4 of a semicircle sits above the x axis, carrying charge +Q, radius r away from the axis. What is the electric field at the point where the middle of the circle would be? (Hint: the electric field in the x-direction cancels out due to symmetry, calculate E(sub y) to find the answer.)

5. An electron carrying charge -9 (where q=1.602e-19 C) is moving along the x axis in the +x direction with a velocity ū(x, y, z) = 5 x 107 cm/s. a. We want to make the electron to curve to the right and eventually go in a circle clockwise in the xy plane by applying a magnetic field. To achieve that, the magnetic field should exert a force on the electron that is perpendicular to its direction of motion. Which...
