Unformatted text preview: 58. The field of each charge has magnitude E=k e = 3.6 × 10−6 N/C . (0.020 m)2 The directions are indicated in standard format below. We use the magnitude-angle notation (convenient if one is using a vector capable calculator in polar mode) and write (starting with the proton on the left and moving around clockwise) the contributions to Enet as follows: (E − 20◦ ) + (E This yields (3.93 × 10−6 130◦ ) + (E − 100◦ ) + (E − 150◦ ) + (E − 76.4◦ ), with the N/C unit understood. 0◦ ) . ...
