(27%) Problem 5: A very long wire, which is horizontal in the plane of the page, has a uniform charge density of 4.5 MC/m. An observation point, P, is also located in the plane page, as shown. P 90 A 50% Part (a) If the separation between the observation point, P, and the wire is 2.6 mm, then what is the magnitude of the electric field, in newtons per coulomb, at P? E = N/C Grade Sum Deductions DoA 50% Part (b) Which statement best describes the direction of the electric field at the observation point, P? O The electric field is directed towards the top of the page. The electric field is directed towards the left-hand side of the page. The electric field is directed into the page. The electric field is directed out of the page. O The electric field is directed towards the right-hand side of the page. O The electric field is directed towards the bottom of the page
