Unformatted text preview: lim (kl9356) – Homework 4 – Weathers – (22202) 1 This printout should have 9 questions. Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points A uniformly charged conducting plate with area A has a total charge Q which is positive. The figure below shows a crosssectional view of the plane and the electric field lines due to the charge on the plane. The figure is not drawn to scale. E E + Q P Find the magnitude of the field at point P, which is a distance a from the plate. Assume that a is very small when compared to the dimensions of the plate, such that edge effects can be ignored. 1. bardbl vector E P bardbl = 4 π ǫ a Q 2. bardbl vector E P bardbl = 2 ǫ Q A 3. bardbl vector E P bardbl = ǫ Q a 2 4. bardbl vector E P bardbl = Q 4 π ǫ a 2 5. bardbl vector E P bardbl = Q 2 ǫ A 6. bardbl vector E P bardbl = Q ǫ A 7. bardbl vector E P bardbl = ǫ Q A 8. bardbl vector E P bardbl = 4 π ǫ a 2 Q 9.9....
