Two point charges (q1 = -2.5μC and q2 = 8.6 μC) are fixed along the x-axis, separated by a distance d = 9.7 cm. Point P is located at (x, y) = (d, d). a. What is Ex(P), the value of the x-component of the electric field produced by q1 and q2 at point P?

b. What is Ey(P), the value of the y-component of the electric field produced by q1 and q2 at point P?
