A beam of protons enters the network of five chambers (4) Value Units shown in (Figure 1) with an initial speed of 500 m/s and moves through the network along the path indicated by the dashed black line. In each chamber, the electric field Submit Request Answer is as specified, ET' = 2.19 mN/C and EY" =-7.00 AN/C , while other components of the electric field in chambers 3 and 5 are zero, and the radius of curvature R is 0.40 m wherever it is shown. Part E For the chamber 5, calculate the component of the magnetic field perpendicular to the path of the protons. Figure
