4. The electric field at 7 = (r,0) due to an ideal dipole p placed at the origin can be expressed as Edipole (1, 0) = 43 (2 cos 0 + + sin 0 6), where 0 is the angle between p and . a) Find the magnitude and the direction of the electric field at point P, which is at a distance y perpendicular to the direction of the dipole. Express your answer without using r or 0. b) Find the magnitude and the direction of the electric field at point Q, which is at a distance x along the direction of the dipole. Express your answer without using 7 or 0. P 18 x 4.
