The magnitude of E is given by 191 2 |E| = E = Ke E = ke where ke is Coulomb's constant and r is the distance, h, of P from 9. We have 191 2 r r1 I = Ke , Need Help? Read It h = (8.99 x 109 Nm/C2)- 4.25 Submit Skip (you cannot come back) 0.433 x 10-6 c) m X The response you submitted has the wrong sign. x 105 N/C. 2 The vector E is along the negative y-direction so it has no horizontal component, that is, Ex = 0, and, for its vertical component, Ey, we have x 105 N/C. Ey Enter a number.
