(6%) Problem 4: Two charges are placed on the x axis with the positive direction towards the right of the page. As shown in the drawing, charge 22 is placed a distance D (upper case) to the right of charge 91. Consider point P which is located between the two charges and a distance d (lower case) to the right of charge 1 91 P 92 Let qu = –60 4C, 22 = +30 pC, D=120 cm and d=15 cm. 50% Part (a) If the electric field at point P is expressed as Ē = E, i, what is the value of Ey , in newtons per coulomb?
