QUESTION 3 [2×3-6 MARKS] An infinitely long wire with linear charge density -+15 nC/m is aligned with the y-axis, and a point charge q-6 nC is sitting static a distance d-10 mm away from the wire on the +x-axis. a) Where on the positive x-axis will the electric field be zero? b) At what position along the vertical dotted line passing through the point charge q. will the net electric field point at 45° above the x-axis? c) If the charge q had a mass m 12 ug and were in circular orbit around the wire, how fast would it have to be moving to maintain its distance d from the wire? d -9 X
